The proposed array processor consists of simple processing elements. The architectural benefits of highly regular, parallel, and pipelined processing elements simplify the design of complex signal processing systems and enable high throughput rate by massive parallel computations. We show the utility of the proposed architecture as a configurable core by mapping inverse discrete cosine transform (IDCT), motion compensation (MC), and inverse quantization (IQ) onto the proposed fabric. In addition, we propose a novel scheme that integrates the inverse quantization part of video decoding into the 2-D IDCT process simplifying computational logics. The results show that a high throughput rate to meet the real-time requirement is effectively achieved by exploiting the properties of both compressed video data statistics and the array processor architecture.","PeriodicalId":158790,"journal":{"name":"IEEE Computer Society Annual Symposium on VLSI: New Frontiers in VLSI Design (ISVLSI'05)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121885657","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}

The design exploits a coefficient distributed arithmetic (CoDA) scheme as opposed to the prevalent data distributed arithmetic (DDA) schemes to achieve low power consumption. The architecture uses no ROMs and uses minimum number of additions by exploiting the redundancy in the adder arrays. The described architecture for the CoDA scheme is implemented on FPGA and has been fabricated on silicon. The fabricated chip computes 8 /spl times/8 2D DCT @ 50 MHz consuming around 137mW of power.","PeriodicalId":158790,"journal":{"name":"IEEE Computer Society Annual Symposium on VLSI: New Frontiers in VLSI Design (ISVLSI'05)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128561702","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}

With the proliferation of embedded multi-processor systems, software support for their memories is becoming an attractive research area in real-time embedded computing. One of the critical problems in embedded real-time multi-processor SoCs (system-on-a-chip) is to reduce the number of off-chip references. This is because frequent off-chip references can be very costly from both performance and power perspectives. In this paper, we propose a novel compiler-driven strategy for reducing the number of off-chip references, which is based on cooperation between the processors in the multi-processor architecture. Specifically, in the proposed strategy, the processors cache data in their local memories, under compiler control, on behalf of each other if doing so reduces the number of off-chip references.","PeriodicalId":158790,"journal":{"name":"IEEE Computer Society Annual Symposium on VLSI: New Frontiers in VLSI Design (ISVLSI'05)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129642965","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}

However, providing security incurs performance and power overheads that need to be limited in resource-constrained embedded environments. Consequently, architectural support to limit these overheads to be incurred only while storing or processing vital data is desirable. In this paper, we present an architecture that provides selective encryption protection for storage and processing protection to power analysis attacks for data marked as requiring security. Further, we show how the code can be transformed to reduce the overhead associated with protecting secure data.","PeriodicalId":158790,"journal":{"name":"IEEE Computer Society Annual Symposium on VLSI: New Frontiers in VLSI Design (ISVLSI'05)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121503170","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}

Multiple sensors/computational architecture, in the form of our eWatch device, is used to infer the activities that the system is encountering, and can provide a platform for context-aware computing. We created an eWatch prototype that senses user activities and notifies them when important messages have arrived. An accelerometer and microphone provide inputs to a model of interruptibility. A vibration motor for tactile feedback and two ultra bright LEDs for visual feedback provide user notification through different vibration patterns and colors. eWatch is transparently integrated into the user's environment, and communicates via Bluetooth. This new class of integrated systems underscores the need for new forms of regularity, constraints, and design structure. Our results indicate the power of our method to accurately determine a meaningful context model while only requiring data from our eWatch device.","PeriodicalId":158790,"journal":{"name":"IEEE Computer Society Annual Symposium on VLSI: New Frontiers in VLSI Design (ISVLSI'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127269172","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}

The key feature of our design is the use of an energy recovering \"boost\" stage to provide an efficient gate overdrive to a highly voltage-scaled logic at near-threshold supply voltage. We have evaluated our logic family using simulation results from an 8-bit carry-save multiplier in a 0.13 /spl mu/m CMOS process with V/sub th/ = 340 mV at 1.4 GHz and a 1.1 V supply voltage, the boost multiplier dissipates 3.44 pJ per computation, achieving 57% energy savings with respect to its static CMOS counterpart.
