Trace data transfer system having burst and minimum threshold inputs

摘要

This invention controls data transmission from a data source to a sink. The data source buffers the data. The data source signaling to transmit data upon storing a burst amount of data. The data source may include a plurality of data sources. A merge unit merges data by receiving and retransmitting data from each data source which signals to transmit and inserting a source identity block each time the merged data is received from a different source.

1. A trace data transfer system comprising:
A. request logic having a valid output lead, a ready input lead, and a threshold control input lead; B. first multiplexer circuitry having a control input, a burst threshold input, a minimum threshold input, and a threshold control output coupled to the threshold control input lead; and C. flip-flop circuitry having a non-inverting output coupled to the control input of the first multiplexer circuitry.
