Abstract
A data processor includes an instruction decoder, an execution unit, a general-purpose register file, and an index-register file. The instruction set for the data processor includes indirect-indexing instructions to facilitate table lookups. When executing such an instruction, the execution unit reads an index stored at an index-register location specified by the instruction. The index refers to a general-purpose register location, which is then read and copied to a general-purpose register location as specified by the instruction. The disclosed execution unit includes four functional units, each with two read ports and a write port so that eight table lookups can be performed in parallel.
