Abstract
A data processing apparatus includes first () and second () functional unit groups, each includes a plurality of functional units and a register file () comprising a plurality of registers. A comparator () receives the operand register number of a current instruction for a functional unit in the first functional unit group, and the destination register number of an immediately preceding instruction for the second functional unit group. A register file bypass multiplexer () selects the data from the register corresponding to the operand number of the current instruction on no match and selects the output of the second functional unit group (hotpath) if the comparator indicates a match. The first functional unit utilizes the output of the second functional unit group without waiting for the result to be stored in the register file.
