Abstract
A data processor includes a first register file including registers, a second register file including registers, a number of which is larger than that of the registers of the first register file, an instruction decoder and an operation unit. The instruction decoder decodes an instruction described in first and second instruction formats. The first instruction format includes a first register-addressing field for designating the first register file. The second instruction format includes a second register-addressing field for designating the second register file, a size of which is larger than that of the first register-addressing field. The operation unit executes an instruction described in the first and second instruction formats using operand data stored in the first and second register files, respectively, based on the instruction decoder, and executes operations in parallel, a number of which is determined by a certain field included in the second instruction format.
