Abstract
A method and an apparatus for data processing between multiple execution units using local and global register bypasses is disclosed. In one embodiment, the device contains a register file, at least two bypass circuits, a plurality of execution units, and a control circuit. Each bypass circuit connects to at least one execution unit. The control circuit, which is coupled to the execution units, limits no more than one clock delay per each execution clock cycle. The control circuit further designates delay clock cycles for handling delays.
