Dynamic selection of a compression algorithm for trace data

摘要

A tracing system includes a trace bus and compression selection circuitry. The compression selection circuitry is configured to receive a trace data input from a source of trace data and determines a compression method for a piece of trace data selected for transmission on the trace bus. The compression selection logic selects the compression method from a set of compression methods based on at least one compression criterion. The tracing system signals the compression method that was used to compress a piece of compressed trace data selected for transmission.
