Abstract
A compressed replay buffer in a first electronic unit of an electronic system holds commands in a table. As commands are transmitted from the first electronic unit to a second electronic unit, the command, along with associated data, command type, and the like are stored in a row in the table. No rows in the table contain 'dead cycles' to indicate that no command was sent on a particular cycle on a bus over which the commands were transmitted. The second electronic unit may request that the first electronic unit replay some number of commands. In response, the first electronic unit uses commands in the compressed replay buffer, along with required timings stored on the first electronic unit, to replay the number of commands requested.
