They concentrate on algorithms for two-level logic implementations, while work on algorithms for multi-level logic implementations is in progress. Input to the system is a description of the FSM in form of a state table. CASTOR generates an appropriate controller consisting of pre- and postprocessing structures around a kernel FSM, which may be a PLA, a ROM or random logic. In the case of a PLA or random logical controller coding constraints are extracted for the kernel FSM. Then these coding constraints have to be satisfied by adequate state assignment algorithms in order to minimize the area of the physical implementation.<<ETX>>","PeriodicalId":205695,"journal":{"name":"[Proceedings] EURO ASIC `90","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123421638","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 task is equivalent to a multidimensional and/or multi objective optimization problem: n-variables functions have to be minimized in an hyperrectangular domain: equality and/or inequality constraints can be eventually specified. The authors propose an efficient algorithm, based on the repeated application of simulated annealing to a certain number of p-variables sub problems, with p<<n. Objective functions are computed through the modular SPICE-PAC simulator, which is controlled by the optimization algorithm.<<ETX>>","PeriodicalId":205695,"journal":{"name":"[Proceedings] EURO ASIC `90","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128460927","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}

A potential catalyst to bring this about is the nascent field of high-level synthesis, which promises to furnish conventional datapath architectures with the power of parallelism and pipelining. This paper reports progress in a high-level IC design tool intended specifically for DSP users, now more than one year in development. While parallelism and pipelining are naturally exploited, novel use is made of synthesis techniques at bit-level, which brings both advantages and disadvantages in comparison to high-level synthesis. The approach is powerful and efficient in high-throughput, fixed-function applications.<<ETX>>","PeriodicalId":205695,"journal":{"name":"[Proceedings] EURO ASIC `90","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124546547","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 IOP is used as a central element in ISA (Industry Standard Architecture)-based peripheral controller applications. In this specific application, it incorporates a comprehensive set of function blocks in addition to the core 32-bit RISC processor. These include an ISA address decoder, a register file compatible with the PC/AT-compatible hard disk controller, a DRAM controller capable of support 16 M bytes of 32-bit memory, an interrupt controller, a DMA controller, a 2 K-byte ROM and a 512-byte RAM. The IOP has been optimized for application requiring high data transfer rates. Burst data transfers up to 40 M bytes per second may be attained with the RISC processor running at 10 MHz. A paging and interleaving DRAM controller is utilized so that slower DRAMs with 100 nanoseconds access times can be used.<<ETX>>","PeriodicalId":205695,"journal":{"name":"[Proceedings] EURO ASIC `90","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130303193","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 system, called Hercules and Hebe, offers many advantages to the designer. First, the system supports constraint-driven synthesis where timing and resource constraints are applied to guide the synthesis decisions. Second, systematic design space exploration is possible, where the designer explores the tradeoff between area and performance to meet the design objectives. Third, logic synthesis techniques are uniformly incorporated within the synthesis framework to provide estimates to guide high-level decisions. Along with a synthesis oriented hardware description language called HardwareC, Hercules/Hebe provides an environment for the design of general synchronous digital circuits, with specific attention to the requirements of ASIC designs. The system has been applied to complex ASIC designs, including the Digital Audio I/O, MAMA, and Bi-Dimensional DCT chips.<<ETX>>","PeriodicalId":205695,"journal":{"name":"[Proceedings] EURO ASIC `90","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122230334","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}

Both basic cells, the current mirrors and the translinear mixed loops, appear to be the most important cells from which elementary building blocks (i.e. followers, conveyors. . .) can be implemented. Then, as demonstrated by some illustrative examples, high performance advanced macroblocks (i.e. amplifiers, filters. . .etc.) will be obtained.
