Abstract
A processor ( ) is provided that is a programmable digital signal processor (DSP) with variable instruction length. A trace FIFO ( ) is provided for tracing a sequence of instruction addresses to assist with software or hardware debugging. In order to conserve space, only the addresses of an instruction just before (M+K, P+Q) and just after (P, R) a discontinuity are stored in the trace FIFO. A sequence of instruction lengths (SEC LPC) is also stored in the trace FIFO so that the sequence of instruction addresses can be reconstructed by interpolating between two discontinuity points (P to P+Q).
