Host-Target Development System

Objective

The objective of the HTDS project is to develop a prototype integrated tool system based on a PCTE environment to support automatic testing, high-level debugging and remote maintenance.
The project aims to establish a framework for the test and debug process between the compiler output and executable target code.
The host-target development area will be examined with a view to specifying a development system. Naked microprocessors, industry standard boards and industry standard computers will be considered as targets. The advantages of distributing the tools between the host and target systems will be considered.
Prototype systems will be realised with tools in the areas of automatic testing, high-level debugging and remote maintenance.
Standard solutions to the communications problems of developing host target systems, will be sought. It is anticipated that results from the CHAMELEON project (1256) will be of help in this task.
The objective of the project was to develop a prototype integrated tool system based on a portable common tool environment (PCTE) to support automatic testing, high level debugging and remote maintenance. A preliminary test and debug specification has been written. This specification includes a full list and description of commands necessary to test and debug executable code in the proposed environments. Two levels of interface are being defined in the process between the compiler output and the execution mapping. The upper level lends itself to the human interface and the lower level to the machine. At the final review a demonstration in a HOOD environment was given. This incorporated diagnostics at the HOOD object design level being executed by running the resultant code on 68000 code emulators. The process visibility generated in the windowing system was good.

Exploitation
This project will engender a common approach to the test and debug phase of system development with the associated standardisation benefits.
