In wireless applications, highly spectral-efficient modulations, such as quadrature amplitude modulation with large number of symbols (256 or above), enables higher bit rate at same bandwidth occupation, at the price of tighter constraints on the error-vector magnitude. This demands for an ultra-low jitter local oscillator (LO). For instance, the 5G new radio for cellular communications at frequencies around 28GHz calls for an integrated phase noise well below -36dBc, translating into an absolute rms jitter well below 90fs, over all the operating conditions. Similar performance is also required to the clock of high-speed analog-to-digital converters not to deteriorate their signal-to-noise ratio (SNR). An SNR of 62dB (i.e., 10 equivalent bits) at 1GHz bandwidth requires a clock jitter well below 130fs.","PeriodicalId":415990,"journal":{"name":"2022 IEEE Custom Integrated Circuits Conference (CICC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121279830","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 subsequent decades, the importance of detecting incoming bombers motivated the advancement of radio detection and ranging (radar) systems where the roundtrip time of a short pulse was used to find the target distance whereas the direction of the antenna was used to localize the target. Later advancements in phased array technology replaced the mechanically scanned antenna with electronically scanned versions enabling faster target localization, and ultimately, tracking multiple concurrent targets. Light detection and ranging (Iidar), initially referred to as laser radar, was developed shortly after the invention of lasers in the $1960mathrm{s}$. The primary early applications were in metrology, military, and scientific discoveries and research.

Delivering a high visual performance for Codec Avatar workloads, however, is a challenging task for mobile SoCs as AR/VR devices have limited power and form factor constraints. On-device, local, near-sensor processing provides the best system-level energy-efficiency and enables strong security and privacy features in the long run. In this work, we present a custom-built, prototype small-scale mobile SoC that achieves energy-efficient performance for running eye gaze extraction of the Codec Avatar model. The test-chip, fabricated in 7nm technology node, features a Neural Network (NN) accelerator consisting of a 1024 Multiply-Accumulate (MAC) array, 2MB on-chip SRAM, and a 32bit RISC-V CPU. The featured test-chip is integrated on a prototype mobile VR headset to run the Codec Avatar application. This work aims to show the full stack design considerations of system-level integration, hardware-aware model customization, and circuit-level acceleration to meet the challenging mobile AR/VR SoC specifications for a Codec Avatar demonstration. By re-architecting the Convolutional NN (CNN) based eye gaze extraction model and tailoring it for the hardware, the entire model fits on the chip to mitigate system-level energy and latency cost of off-chip memory accesses. By efficiently accelerating the convolution operation at the circuit-level, the presented prototype SoC achieves 30 frames per second performance with low-power consumption at low form factors. With the full-stack design considerations presented in this work, the featured test-chip consumes 22.7mW power to run inference on the entire CNN model in 16.5ms from input to output for a single sensor image. As a result, the test-chip achieves 375 µJ/frame/eye energy-efficiency within a 2.56 mm2 silicon area.","PeriodicalId":415990,"journal":{"name":"2022 IEEE Custom Integrated Circuits Conference (CICC)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126114725","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}

This specialized hardware targets one of two categories-either operating in datacenters or on mobile devices at the network edge. While energy efficiency is important in both cases, the need is extremely stringent in the latter class of applications due to limited battery life. Several techniques have been used in the past to improve the energy efficiency of these accelerators [3], including reducing off-chip DRAM access, managing data flow across processing elements as well as in-memory computing (IMC) by exploiting analog processing of data within digital memory arrays [4].","PeriodicalId":415990,"journal":{"name":"2022 IEEE Custom Integrated Circuits Conference (CICC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127183668","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}

Basu","doi":"10.48550/arXiv.2203.01413","DOIUrl":"https://doi.org/10.48550/arXiv.2203.01413","url":null,"abstract":"The bio-inspired asynchronous event-based neuromorphic vision sensors (NVS) are introducing a paradigm shift in visual information sensing and processing [1]. The feature of event-driven operation makes it ideal for low-power operation in the Internet-of-Things scenario such as traffic monitoring. However, the inherent noise in the sensor causes redundant wake-up operation and reduces tracking performance [2]. Energy efficient in-memory computing (IMC) based denoise operation allows blank-frame detection to gain 2X energy savings. Further energy savings can be obtained by exploiting spatial redundancy-objects usually occupy a small part ~5% of the frame in traffic monitoring [3]. Hence, region proposal (RP) is required to detect the region of interests (ROIs) in a valid frame along with their bounding box location coordinates, as shown in Fig. 1. For binary images, the conventional connected component labeling (CCL) algorithm [4] can propose ROIs by raster scanning the whole frame, but leads to longer search time and higher computing energy due to von Neumann operation. The promising IMC approach [3] has high energy efficiency, but has limited accuracy due to a simple algorithm constrained by in-memory operations as well as object fragmentation due to smooth surfaces (e.g. car windows) that do not generate events. In this work, we present a hybrid memory bit cell-collocated SRAM and DRAM (CRAM) consisting of 11 transistors for IMC-based image restoration (IR) and RP. The proposed CRAM supports image storage in SRAM and DRAM modes, denoise and region filling in diffusion mode and RP algorithm in projection mode.","PeriodicalId":415990,"journal":{"name":"2022 IEEE Custom Integrated Circuits Conference (CICC)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116671932","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}

Principled mathematical solutions for SLAM involve filtering-based or non-linear optimization-based (Fig. 1a), where the latter recently shows higher robustness but with intensive computation. Prior ASICs [1], [2] and FPGAs [3], [4], [5] have accelerated SLAM on hardware, but they usually target one specific design.
