While series-connected voltage regulators [1], [2] and arithmetic countermeasures like heterogenous Galois-field arithmetic [3] provide acceptable levels of side-channel leakage suppression, they cannot defend against determined adversaries. Random additive masking [4] on the other hand, provides a provably-secure solution [5] that disrupts first-order correlations between measured power/EM signatures and secret keys, while incurring $2times$ overhead in area and power consumption. In this paper, we demonstrate a reconfigurable AES accelerator fabricated in Intel 4 CMOS process with minimum-time-to-disclosure (MTD) $> 1text{B power}/text{EM}$ traces in on-demand SCA-resistant mode, while providing a $2.2times$ boost in encryption performance during a dual-core mode of operation (Fig. 34.4.1). When coupled with side-channel attack detection techniques [6], [7], this approach allows the user to operate at $> 2times$ AES throughput during the safe mode of operation in trusted environments, with the ability to quickly trade-off throughput for a higher level of SCA-resistance when the onset of an attack is detected. In the blind-bulk mode of operation, the accelerator randomly switches at a user-specified rate between SCA-resistant and dual-core modes while encrypting bulk data, providing $1.14-text{to}-1.6times$ boost in encryption throughput with measured MTD $> 50mathrm{M}$ traces.","PeriodicalId":6830,"journal":{"name":"2022 IEEE International Solid- State Circuits Conference (ISSCC)","volume":"198 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2022-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84960940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, to compensate for the mm-wave high path loss, large-scaled MIMO arrays have become essential. This calls for compact high-performance mm-wave 5G front-end electronics to integrate many MIMO channels on the same chip for low cost and low form factor. A main challenge for mm-wave 5G MIMOs is to integrate both front-end transmitter (TX) and receiver (RX) chains in each array pixel with a minimum silicon area to form a co-apertured low-cost array [1]. The conventional TRX architecture often consists of a PA and an LNA placed in parallel and combined by a T/R switch to control the TX/RX mode. Although this topology eases the design, it faces chip area increase due to many separate matching networks for the PA/LNA/switch, as well as the switch loss that degrades the PA output power (Pout) and LNA noise figure (NF). On the other hand, though bi-directional mm-wave front-ends are gaining popularity, existing designs only show narrow bandwidth and very limited PA Pout and efficiency.","PeriodicalId":6830,"journal":{"name":"2022 IEEE International Solid- State Circuits Conference (ISSCC)","volume":"11 1","pages":"322-324"},"PeriodicalIF":0.0,"publicationDate":"2022-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84065721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, pre-fetch sizes have also increased with DRAM generations, meaning an increased number of global bus lines. An increase to this number is limited as it also increases the chip size; instead, the data-rate per lane can be increased for higher throughput [1]. As the global bus lines are on-chip wires in a DRAM chip, they can be driven capacitively. Prior work [2], [3] has shown the superior efficiency of capacitive drivers, over conventional repeaters, in driving on-chip wires at the cost of a reduced voltage swing. However, as there is no well-defined DC level on the capacitively-driven wires [4], wire biasing is fraught with implementation challenges [3]. To define the DC potential on the interconnect, prior work sent signals differentially [2], [4], [5] or dissipated static power to define the DC level [3].

The conjoined process of transaction validation and currency minting, known as mining, employs the compute-intensive SHA256 double hash as proof-of-work. The one-way property of SHA256 necessitates a brute-force search by sweeping a 32b random input value called nonce. The 232 nonce space search results in energy-intensive pool operations distributed on high-throughput mining systems, executing parallel nonce searches with candidate Merkle roots. Energy-efficient custom ASICs are required for cost-effective mining, where energy costs dominate operational expenses, and the number of hash engines integrated on a single die govern platform cost and peak mining throughput [2]. In this paper, we present BonanzaMine, an energy-efficient mining ASIC fabricated in 7nm CMOS (Fig. 21.3.7), featuring: (i) bitcoin-optimized look-ahead message digest datapath resulting in 33% Cdyn reduction compared to conventional SHA256 digest datapath; (ii) a half-frequency scheduler datapath, reducing sequential and clock power by 33%; (iii) 3-phase latch-based design with stretchable non-overlapping clocks, eliminating min-delay paths; (iv) robust ultra-low-voltage operation at 355mV using board-level voltage-stacking; and (v) mining throughput of 137GHash/s at an energy efficiency of 55J/THash.","PeriodicalId":6830,"journal":{"name":"2022 IEEE International Solid- State Circuits Conference (ISSCC)","volume":"42 1","pages":"354-356"},"PeriodicalIF":0.0,"publicationDate":"2022-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80939988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Power dissipation and latency are major concerns in AloT devices, usually operating in random-sparse-event (RSE) scenarios (Fig. 22.7.1, top). Being event-driven on the system level, an always-on wake-up system (WUS) detects the valid RSEs energy-efficiently and intelligently, and upon detection turns on the power-hungry high-performance system (HPS). Being event-driven on the module level, a prior WUS [1] uses asynchronous feature extraction and synchronous convolutional neural network to detect the RSEs, consuming 148nW-to-1.68µW with 348ms latency. On the circuit level, the Spiking Neural Network (SNN) gives natural event-driven property. However, the prior SNN works did not fully explore this nature. An SNN circuit [2] achieves keyword spotting task at 205nW-to-570nW, but the framing method causes 100ms latency and is not true real-time. The SNN core in [5] uses synchronous digital design, which consumes significant power by the clock tree. The asynchronous-in-global synchronous-in-local [3]–[4] SNN circuits use local clock signals. They need arbiters in each layer to sort the spikes, weakening the parallelism and timing; additionally, the separation of storage and computing consumes more energy for data movement.","PeriodicalId":6830,"journal":{"name":"2022 IEEE International Solid- State Circuits Conference (ISSCC)","volume":"32 1","pages":"372-374"},"PeriodicalIF":0.0,"publicationDate":"2022-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83182851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, SPAD-based direct time-of-flight (D-ToF) sensors have emerged as LiDAR sensors because they offer a longer maximum detectable range and higher background light immunity than indirect time-of-flight (I-ToF) sensors with photon-mixing devices [1]. However, their complicated front- and back-end blocks to resolve ToF values as short as 100ps require high-resolution TDCs and several memories, limiting the spatial resolution and the depth accuracy in short ranges. To address this issue, alternative architectures combining both D-ToF and I-ToF techniques have been reported [2, 3]. Direct-indirect-mixed frame synthesis provides accurate depth information by detecting phases in short ranges while creating a sparse depth map with counting photons in long ranges [2]. A two-step histogramming TDC is used in [3] where a coarse D-ToF discriminates distance roughly and a fine I-ToF extracts depth precisely.

Compared to other autostereoscopic techniques, factored displays provide greater depth of field, larger field of view, and smoother perspective switching without sacrificing image resolution. Figure 33.3.1 shows an example: a light field consisting of $7times 7$-perspective multi views (MVs) is factorized into a set of dual-layer display views (DVs), and displaying the front and rear DVs on two corresponding LCDs can multiplicatively approximate the light field for 3D vision. A higher rank of factorization generates more frames for time-multiplexed display and can improve 3D fidelity with more computation. However, the light-field factorization demands massive memory bandwidth and large computation complexity and becomes a bottleneck for real-time factored displays. For instance, 126.8GB/s of DRAM bandwidth and 4.7TFLOPS of computation are required in a rank-4 factorization at 720p HD 30fps. It is expensive and energy-inefficient to realize these demands in general-propose processors. This paper presents a light-field factorization processor to address the design challenges of memory bandwidth and computational complexity through three key contributions: 1) a half-block-based factorization (HBBF) flow to decouple DRAM access from the iterative nature of factorization to save DRAM bandwidth; 2) a sparse-ray-sampling (SRS) method which reduces DRAM bandwidth and hardware complexity simultaneously; and 3) INT-hybrid optimization for the computation of light-field factorization to save chip area.","PeriodicalId":6830,"journal":{"name":"2022 IEEE International Solid- State Circuits Conference (ISSCC)","volume":"7 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2022-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86491223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Closed-loop neuromodulation is a promising solution to epileptic seizure control through an implantable device that delivers stimulation when seizures are sensed. Figure 33.2.1 shows an overview of a closed-loop neuromodulation system that includes a neural-signal acquisition unit for extracting EEGs, a neural signal processor for sensing seizures, and a stimulation unit for electrical stimulation. For epileptic states, a seizure onset indicates where a seizure begins, followed by intense brain activity. Several seizure detectors [1] [2] having reasonable performance have been proposed to sense seizures after onset. However, patients may still suffer from epileptic syndromes, depending on the severity of the seizures. The syndromes can be eliminated if the seizures can be predicted before onset. This also reduces the amount of required stimulation current, thereby extending the battery life of the implantable device. However, the computational complexity of an accurate seizure prediction algorithm is very high, considering a machine learning kernel is usually embedded to tackle the time-varying characteristics of EEGs adaptively. Up to tens of minutes is needed for seizure prediction on a high-end CPU and a real-time, energy-efficient seizure predictor has never been demonstrated in the literature.
