  • MicroProgrammed computer simulator tools
    IEEE Transactions on Education, 1990
    Co-Authors: Michal Cutler, Richard R. Eckert


    A versatile microAssembler and Assembler Program is described that was developed to facilitate the preparation of symbolic microPrograms and assembly language Programs for use with the microProgrammable computer simulator ET (educational tool) previously reported by the authors (see ibid., vol.E-30, p.135, Aug. 1987). The microAssembler Program takes as input a microProgram source file written in symbolic form and produces files ready for loading into the simulator’s control ROM and address ROM. In addition, a file containing the mnemonics and corresponding op-codes of each instruction in the instruction set of the machine being simulated by the microProgram is created. The Assembler Program uses this file together with a user-written symbolic assembly language source Program and produces a file containing machine language object code ready for loading into the simulator’s RAM. Both the microAssembler and the Assembler also produce list files that may be examined by the user. Students of computer architecture indicate that use of these tools, in conjunction with the ET simulator, greatly simplifies the task of learning how microProgrammed computers function. >

Marcello D'antiochia – One of the best experts on this subject based on the ideXlab platform.

    Publications of the Astronomical Society of the Pacific, 1992
    Co-Authors: Giovanni Bonanno, Bruno Fedel, Marcello D'antiochia


    We describe the astronomical image acquisition system developed at Catania Astrophysical Observatory, based on a VMEbus and the Motorola MVME-147 Single Board Computer (SBC) running the real-time OS-9/68000 Professional operating system. Also described are the hardware architecture chosen and the software strategies used for the image acquisition from a CCD controller with improved flexibility and speed of the operation. The CPU directly controls data acquisition in sychronization with the CCD electronics, by disabling the operating system and running an Assembler Program, which allows us to use only three standard VME boards and guarantees a high throughput and high data accuracy.

  • An ASIC approach to power IC design
    Proceedings of the 2nd International Symposium on Power Semiconductor Devices and Ics. ISPSD '90., 1
    Co-Authors: P.w. Shackle, I.t. Wacyk, J.l. Woo


    A design methodology for mixed analoddigitupower ICs has been developed. It uses a cell library of common power control functions and a device lsyout compiler for automatic generation of power devices. A proprietary mixed mode simulator uses models stored with each cell design to simulate complete chips in their power system. Placement and routing of control circuitry is achieved with commercially available tools. The control circuitry is united with the power devices, drivers and bonding pads with a chip Assembler Program.
