When the number of wires available on a chip is limited, it is sometimes congested and increased la-tency can degrade the parallel application performance. The selective data compression has been proposed to mitigate such network congestion by compressing and decompressing packets based on the packet length and traffic situation. However, since the algorithm does not care the location of nodes, the compression and decompression are performed even when the packet is transferred between neighboring nodes. This paper proposes a distance aware (DA) compression mechanism to select whether the packet should be compressed by the distance to the destination. The packets to the nodes whose distance is larger than threshold level are compressed with a run-length loss-less compression at the sender's network interface and de-compressed at the receiver's network interface. Cycle level network simulation results show that the selective compression method achieves up to 45% bandwidth improve-ment with 1.26 times increase of the latency.","PeriodicalId":150801,"journal":{"name":"2022 IEEE 15th International Symposium on Embedded Multicore/Many-core Systems-on-Chip (MCSoC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124662047","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}

Therefore, in this work a hardware efficient algorithm called Integer-Net which is based on approximate floating-point operations is studied for edge DNN inference deployment. This algorithm uses integerized floating-point arithmetic with a scalar correction for the matrix operations. Electroencephalo-gram (EEG) signal based automatic high-speed epileptic seizure detection using Integer-Net convolutional neural network (CNN) was hardware-implemented on Zynq-7000 SoC to characterize performance efficiency and hardware resources utilized against the full precision model. Implementation was benefited by the accelerated outputs, leveraged the optimum on-board resources, and at the same time with the help of configurable integer bit-width, facilitated keeping the accuracy close to the original model. This is the first time, Integer-Net based designs and their novel hybrid versions were employed and investigated for the hardware acceleration of a CNN network for seizure detection on FPG A. A latency acceleration of 5.65x with the on-chip memory usage reduction factor of 5.99x was achieved by the optimized hybrid integerized CNN model.","PeriodicalId":150801,"journal":{"name":"2022 IEEE 15th International Symposium on Embedded Multicore/Many-core Systems-on-Chip (MCSoC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127988977","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 the micro-architecture, multi-processing and multi-threading arose as fusing highly parallel processing and the growth of semiconductor manufacturing technology. It has caused a paradigm shift in computing chips and led to the many-core processor age, such as NVIDIA GPUs, Movidius Myriad, PEZY ZettaScaler, and the project Eyeriss based on a reconfigurable accelerator. Wherein packed SIMD (Single Instruction Multiple Data) vectorizations attract attention, especially from ML (machine learning) applications. It can achieve more energy-efficient computing by reducing computing precision, which is enough for ML applications to obtain the results with low-accuracy calculations. In other words, accuracy-flexible computing needs to allow splitting off one N-bit ALU (Arithmetic Logic Unit) or one N-bit FPU (Floating-Point Unit) into multiple $M$-bit units. For example, a double-precision (64-bit operands width) FPU can be split into two single-precision (32-bit operands width) FPUs, or four half-precision (16-bit operands width) FPUs. Consequently, instead of executing one original operation, a packed SIMD vectorization simultaneously enables executing two or four reduced-precision operations. This article proposes a packed SIMD vectorization approach, which considers the Dynamically Reprogrammable Architecture of Gather-scatter Overlay Nodes-Compact Buffering (DRAGON2-CB) many-core overlay architecture. In particular, this article presents a thorough comparative study between packed SIMD using dual single-precision and quad half-precision FPU-only many-core overlays compared to the non-vectorized double-precision version.","PeriodicalId":150801,"journal":{"name":"2022 IEEE 15th International Symposium on Embedded Multicore/Many-core Systems-on-Chip (MCSoC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130181582","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}

Due to abun-dant and inexpensive computational capacity, computationally intensive machine learning applications have gained a lot of traction and are currently being used in a wide range of application domains. Furthermore, there is an increasing trend toward developing hardware accelerators for machine learning applications for embedded edge devices where performance and energy efficiency are critical. Although floating-point operations are frequently used for accuracy in these hardware accelerators, reduced width floating point formats are also used to reduce hardware complexity and thus power consumption while pre-serving accuracy. Mixed-precision DNN, vectorization techniques, and any-precision DNN concepts have also proven to boost performance, energy efficiency, and memory bandwidth. In this paper, we propose the design of a vectorized floating-point adder/subtractor that can handle arbitrary length floating-point formats with varying exponent and mantissa widths. The whole idea of this paper is to bring flexibility to each layer in a DNN model for arithmetic operations; depending on the requirement of computation of each layer, exponent width and the floating-point format are chosen dynamically. In comparison to existing designs in the literature, the proposed design is $1.69times$ area and $1.61times$ power-efficient, and it supports true vectorization with no restrictions on exponent and mantissa widths.","PeriodicalId":150801,"journal":{"name":"2022 IEEE 15th International Symposium on Embedded Multicore/Many-core Systems-on-Chip (MCSoC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124824833","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}

To achieve speedups for numerical calculation using mixed-precision computation, it is necessary to tune software performance with respect to not only execution speed but also computation accuracy and power consumption. This increases the overall cost of tuning. Autotuning (AT) is one of the candidates among several technologies available for reducing the cost associated with tuning the software performance. In this study, we propose a method for AT to obtain speedups with respect to computation accuracy and power consumption. The proposed AT method uses an AT language that changes computation accuracy of the original code to mixed-precision by combining double and single precisions. Performance evaluation was carried out by using the Fujitsu PRIMEHPC FX1000, which is a “Fugaku” type supercomputer installed at the Information Technology Center, Nagoya University. The proposed method achieved a 1.5x reduction in execution time and energy consumption while retaining reasonable accuracy degradation from the original code of a global cloud resolving model.","PeriodicalId":150801,"journal":{"name":"2022 IEEE 15th International Symposium on Embedded Multicore/Many-core Systems-on-Chip (MCSoC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133743264","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}
