Abstract

In this paper we introduce the design and implementation of a testable and reconfigurable interrupt controller circuit that provides an efficient interface for working with many standard 8- and 16-bit microprocessors. The proposed architecture differs from the conventional systems in terms of fast interrupt response time, connection capability of a large number of peripheral devices without any performance degradation, programmability, and reduced hardware complexity. In addition, it incorporates testable and fault-tolerant techniques making it reconfigurable in case of a fault. This circuit finds attractive in many real-time computation critical applications in industrial control environment that require highly reliable operation.
