    A microprogram assembler which can assemble code for any user-defined target machine, i.e. a metamicroassembler, is described. Its most important feature is a definition phase where a description of the actual microinstruction set is given once for all, using a simple definition language. Within this definition phase, simple semantic controls may be introduced to facilitate the detection of errors... View full abstract»

  • Classification under permutations of the ternary functions of two variables

    The paper presents a classification of the ternary functions of two variables by application of the permutation group either to the input variables or to the output, and by the interchange of the input variables. A set of invariants for the characterisation of the equivalence classes resulting from this classification is introduced, and also an algorithm for their calculation. As an alternative ch...

    With a dynamically microprogrammable computer, the user has the opportunity to tune the architecture to a given application in order to minimise its execution time. The program must be analysed to identify all the instruction sequences/segments, loops and functionally equivalence sequences) which can constitute new instructions. A set of parameters are associated with every sequence for selecting ... View full abstract»

    The paper presents a family of algorithms for evaluating the elementary mathematical functions including division, sine, cosine, tangent, arctangent, logarithm, exponential and square root. The algorithms are based on continued products and continued sums, and generate the sum on a 2-bit-at-a-time basis. The only operations required are shifting, adding, subtracting and recall of prestored constan... View full abstract»

  • Interactive image-processing software for a microcomputer

    Publication Year: 1981 , Page(s): 165 - 171

    The software used in a microprocessor-based interactive image-processing system is described. Techniques suitable for the analysis of such software are outlined and the effect of processing time is considered. The sytem hardware and operating-system software are briefly reviewed and the design of the interactive software is described. Processing times and the sizes of routines written in Intel 808...
