AccVHDL.pdf "Accelerated Verification of Digital Devices Using VHDL" This paper presents two aspects for improving the verification of microprocessors; program-less verification, and methods for handling large differences in abstraction level between a reference model and the actual design. Program-less verification is a type of pseudo random verification where the notion of a software program executing on the microprocessor has been abandoned. This paper will be presented at the VHDL Users' Forum in Europe in Lausanne (CH), September 1998.

Iris.pdf "A Single-chip CCSDS Packet Telemetry and Telecommand Based Microcamera" By applying the packet telemetry and telecommand standards endorsed by the European Space Agency (ESA) and the Consultative Committee for Space Data Systems (CCSDS) to a microcamera, the need for support from the on-board data handling system can almost be eliminated. If the microcamera is designed with interfaces that fully match those of the telemetry and the telecommand subsystem, the additional interface components will be reduced to simple transceivers.

ReadOut.pdf "Miniaturised Microcontroller based Read-out Electronics for Space Applications" The Particle Detector Front End (PDFE) ASIC together with an 8052 based microcontroller forms a chip set being developed by the European Space Agency (ESA) for compact low cost scientific energetic particle instrumentation. Driving requirements of low noise and power consumption led to the selection of a single configurable analogue channel followed by an internal 8-bit ADC. Low mass and volume necessitated for space applications require on-chip integration of supporting functions such as discriminators, independent coincidence event detection and an efficient serial control interface.
