Poorly chosen processors can either under perform very badly or over perform but with high cost. Most previous work on performance estimation are based on generating the development tools, i.e., compilers, assemblers etc from a processor description file and then additionally generating an instruction set simulator to get the performance. In this work we present a simpler strategy for performance estimation. We propose an estimation technique based on the intermediate format of an application. The estimation process does not require the generation of all the development tools as in the prevalent methods. As a result our method is not only cheaper but also faster.","PeriodicalId":328550,"journal":{"name":"Fifth International Workshop on System-on-Chip for Real-Time Applications (IWSOC'05)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130499237","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}

Designers spend up to 70% of their time developing and running tests to verify the functionality of their systems based in 2004 IC/ASIC Functional Verification Study (2005). Running regression suites against the design can take up to several years of CPU time to complete. In this paper we show how existing software code bases can be used to reduce the time to develop and execute verification tests. These techniques can be applied to both unit and system level verification. As shown in various hardware/software co-verification tools as stated in R. Klein (1996) and M. Stanbro (1998), the overall load on a simulation can be reduced by eliminating code and data references from the set of bus cycles generated by the processor model. These same techniques can be applied by hardware designers and verification engineers to use firmware, hardware diagnostics, and other software as a basis for creating functional verification tests. This software is often available from prior versions of the design or other groups on the design team. Simulation run-times can be reduced by partitioning the processor's memory space between the logic simulation and the processor model.","PeriodicalId":328550,"journal":{"name":"Fifth International Workshop on System-on-Chip for Real-Time Applications (IWSOC'05)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123502317","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}

Two quantization schemes are studied namely the uniform time domain (UQ) and the non uniform time domain (NUQ) quantizers. It is shown that the latter scheme not only permits to linearize the non-linear response of a PWM vision sensor but also allows to significantly speed-up the conversion time particularly for wide dynamic range and lower coding resolution.

Specifically, just as open source has spawned a revolution in the technical, business, and legal model for software, open hardware will provide a swell of collaborative innovation that will create entirely new markets and provide significant business benefits to the most creative, most reliable, and most adaptable semiconductor, EDA, system-on-chip (SoC) and systems houses. The open-source software stack with Linux as its cornerstone is increasingly the preferred choice for newly venture-funded companies. Open hardware will also change the world of SoC venture investing. While the degree of openness and the business model may vary, SoC products have to be increasingly developed through a collaborative model that helps assemble IP blocks and services from multiple sources. In this paper we describe the open standards model for hardware, chip, and tool innovation, and we argue the a systematic IP valuation methodology will help the success of this environment, in that it will allow each member of the value chain - especially small VC-backed companies - to capture enough value to desire to participate.","PeriodicalId":328550,"journal":{"name":"Fifth International Workshop on System-on-Chip for Real-Time Applications (IWSOC'05)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127154247","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}

As the amount of transistors on a chip continues to increase, so does the possibility to integrate more functionality onto every chip. By combining general-purpose and application-specific hardware, it is possible to integrate the complete baseband part of a 3G base station on a single chip. Such a single-chip base station has been modeled from a communication perspective without full implementations of the processing elements. The system has been scheduled and implemented as a traffic model for a network on chip simulator. Simulation results show perfect adherence to the schedule already at a network clock frequency of 75 MHz. The overall network usage is relatively low except for the area closest to the radio interfaces. This allows for other messages, e.g. control related, to be transported over the network during the gaps in the communication schedule.","PeriodicalId":328550,"journal":{"name":"Fifth International Workshop on System-on-Chip for Real-Time Applications (IWSOC'05)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127745433","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 this talk we describe design trends in high-speed serial links from two complementary viewpoints. On one hand we have improvements of the channel through microwave engineering of the passive interconnects/backplanes, and on the other hand a trend toward increased sophistication of the serial link circuits, employing more and more of the communications techniques to compensate for the channel and noise. We describe recent breakthroughs in passive backplane design as well as give some predictions about the capacity of the typical backplane interconnect channels. By looking at the target interconnect applications, like 10-100Tb/s routers, it is clear that both the data rate and power have to improve by an order of magnitude each, to achieve the design goal with manageable physical dimensions of the system. This means an improvement of two orders in magnitude in energy cost per bit, from current designs. We believe that the emerging link design trends like multi-tone signaling and channel-and-circuit-aware coding have the promise to fulfil this task.","PeriodicalId":328550,"journal":{"name":"Fifth International Workshop on System-on-Chip for Real-Time Applications (IWSOC'05)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130757464","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}
