A method and system for performing digital signal processing operations in a computer system are disclosed. Digital Signal Processing operations such as multiply and add (MADD) or multiply and subtract (MSUB) can be performed by general-purpose microprocessors. The DSP operations are directed to n-bit operands that are in m-bit registers. The register size (m) may be a multiple of the operand size (n). For example, the DSP operations may utilize 32-bit registers with 16-bit or 8-bit operands, or the DSP operations may utilize 64-bit registers with 32-bit, 16-bit, or 8-bit operands.
