    The paper presents an integrated procedure, called MCS, for the automated synthesis of microprogrammed controllers in digital systems at the register-transfer (RT) level. To MCS there are two major inputs: a description of the data path of the digital system and a behavioural description of the digital system at the RT level. The result given by MCS is a cost effective controller which can drive t... View full abstract»

  • Performance evaluation of a clustered multiprocessor organisation using an approximate Markov model

    Publication Year: 1987, Page(s):222 - 230

    An approximate Markov model is developed to analyse a clustered multiprocessor interconnection system for processor memory communication. In the proposed network, processors and memories are grouped into clusters utilising locality of communication. Within any cluster processors communicate with the memories through a small crossbar; a synchronous TDM bus interconnects the different clusters. The ... View full abstract»

  • Highly parallel processors in military systems

    Parallelism has found its way into programmable processors as well as dedicated engines such as FFT and digital filters. However, choices of machine architecture are still open. The authors have evaluated two contrasting types to test their versatility and to compare their performance on algorithms related to military applications. Fine-grain SIMD, and coarse-grain MIMD machines (MilDAP and Transp... View full abstract»

  • Optimising accelerator for CAD workstation

    Publication Year: 1987, Page(s):214 - 221

    Sequential versions of those optimisation algorithms which are based on random search heuristics are often too slow to be of value to the interactive user of a CAD workstation. A significant gain in speed can be achieved by using concurrent algorithms to drive an optimising accelerator attached to the workstation. The paper discusses the design and performance of a hardware accelerator which incor... View full abstract»

  • Image processing for electronic document storage

    Publication Year: 1987, Page(s):196 - 201
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (916 KB)

    Reos is a document image processing system which stores images of paper documents as a bit map on optical discs. These images are displayed on a CRT at a lower resolution compared to the stored data. The conversion and display of the stored information must be performed quickly to achieve an acceptable system response time; since even highly optimised software could not process more than a few tho...

  • Systolic architecture for matrix triangularisation with partial pivoting

    Publication Year: 1987, Page(s):208 - 213
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (384 KB)

    A systolic array for triangularisation of dense matrices, using Gaussian elimination with partial pivoting, is presented. The adopted algorithm is a slightly modified version of the traditional partial-pivoting algorithm. The modification is aimed at eliminating the need for global communications, without jeopardising the numerical stability of the algorithm. The array triangularises an n*n dense ...

  • Self-test: the solution to the VLSI test problem?

    Publication Year: 1987, Page(s):190 - 195
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (488 KB)

    Built-in self-test (BIST) is emerging as an important option for testing VLSI application-specific integrated circuits (ASICs). The advantages of BIST are reviewed in relation to the particular test requirements imposed by ASICs. A suite of programs are described that facilitate the incorporation of BIST into ASIC designs. The programs comprise a high-level planning tool, operating from functional... View full abstract»
