Abstract
A circuit arrangement and method support data dependent instruction decoding, whereby instructions are decoded, in part, using decode data that is stored in operand registers identified by such instructions. An instruction may include an opcode and at least one operand that identifies a register. During execution of the instruction, the instruction is first decoded using the opcode, and then decode data stored in the operand register is retrieved and used to further decode the instruction, e.g., to select from among a plurality of operations or instruction types associated with the same opcode.
