Abstract
A high-performance register file is implemented in a multi-block structure consisting of sub-arrays and associated multiplexing circuits. For a given port, the outputs of all multiplexer circuits are dotted together to form a single global output. The multiplexer circuits may be completely external to the cells ('standard' approach), or distributed and integrated into the cells ('alternate' approach). The register cells arranged as such, may or may not contain extra latches, pass gates, and controls arranged so that the file may be fully tested via LSSD.
