Abstract

This report describes the results of implementing an interrupt handler totally in ADA for a MicroVAX II/VAXELN 2.3 target system, the VAXELN 1.1 ADA compiler, and a KWV11-C programmable real-time clock. It provides an overview of VAXELN interrupt handlers and the operation of the real-time clock; discusses and demonstrates the use of VAXELN kernel services to establish a link between the clock's interrupt and the starting address of an interrupt service routine; presents an ADA package of interfaces to the KWV11-C device; provides ADA source code examples demonstrating the use of this package; and presents relevant observations, recommendations, and measurement results.
