    A colour raster display system based on picture encoding is described. Encoding pictures as a means of data compression has a long history and is a technique of interest to anyone working with complex pictures. Its primary value is the lower bandwidths required of transmission channels, but its more frugal use of store is not to be overlooked. A quad tree as a means of encoding area-coherent pictu...

    In this paper the applicability of magnetic-bubble memories to the processing of inverted files is discussed. Four novel models of magnetic-bubble memories are presented to demonstrate storage structures and data processing. The first model employs an organisation of major/minor loops. On the basis of such an organisation a uniform ladder is formed so that the data can be rearranged by using four ... View full abstract»

    A convergent algorithm is introduced which solves the exact system relating the Lagrange multipliers and the projections using the successive relaxation method without any approximation. The system gives the minimum-energy solution which is different from that of the convolution algorithm, but it is the same as the ART reconstruction except that it discretises the Lagrange multipliers instead of t...

  • Technical note. Overflow detection in a redundant residue number system

    A new approach, based on redundancy techniques to detect residue arithmetic overflow, is presented. The detection, when applied to residue systems having residue-to-binary decoders, only requires an additional residue encoder to function. View full abstract»

  • Technical note. Approach for register allocation in microprogram generation

    Publication Year: 1984

    A dynamic procedure for the allocation of internal registers of a microprogrammable system is described. The rules of this procedure are developed to yield an optimal allocation that minimises the execution time of the microprogram generated. The method assumes that the control flow of the program to be microcoded is represented by a directed graph. The allocation and deallocation of the variables... View full abstract»
