GD80 is a modular family of refresh, vector-type graphic displays. Five microprocessors for different tasks communicate on two separate busses using interprocessors interrupts, memory windows and shared memory with hardware supported mutual exclusion. Two identical 8 bit microprocessors are dedicated for peripheral handling and communication, two 16 bit microprogrammable bit-slice processors for picture generation and display list processing, and a 48 bit one for fast floating point arithmetic calculations and matrix-vector transformations. This paper describes the main building blocks, the multiprocessing methods and some typical configurations built using the modules.

This paper describes a way of increasing systems performance by adding microcode to an existing CPU. Other changes in hardware and software are very small. The CPUs are designated 5950 and 5951, respectively, and are used in different models of the Datasaab Series 16, a family of small business sytems.

The drive towards rationalization of energy consumption has led to a more frequent use of thermal energy meters in distribution systems using piped fluids. In this line a measuring system, which operates on the basis of the fluid flowrate and temperature signals, has been realized. The system determines the energy measurement by means of a programmable processing unit. The most salient special features of this part of equipment are illustrated, as well as the performance capability obtainable.
