Microprocessor Debug Tool Based on IBM Series 1 System

In the development of a microprocessor based system, one of the major problems is how to access and control the hardware for testing and debugging. One method is to provide a tool capable of controlling the microprocessor and its related hardware. This article describes the software development of such a tool, specifically a computer system.

The tool developed is based on an IBM Series 1 Computer System. The microprocessor-based system to be controlled consists of two microprocessors, their respective memories, a scratch memory shared by both processors, and hardware input/ output registers.

The IBM Series 1 system test tool provides the following capabilities:

Data Management: Load and save the executable microprocessor instruction file from or to a diskette; display and alter this data set and write it to, or read it from, each microprocessor memory. Transfer the content of the shared scratch memory to and from diskette, and display and alter it. Access the general purpose and input/ output registers to display their contents and modify them.

Communications: Through the IBM Series 1 Direct Program Control (DPC), send and receive data and control signals to the microprocessors.

Control: The IBM Series 1 controls the microprocessors to ensure data transfer between the IBM Series 1 and the microprocessor storage.

Hardware Debug Aid: IBM Series 1 executes its own DPC adapter diagnostics for basic working condit...
