ABSTRACT:
A microprocessor having a saturation operation unit comprising a decoder 220 for decoding a 4-bit saturation operation bit length data item into a 16-bit value, a decoder 221 for decoding a 5-bit saturation operation bit length data item into 1 to a 32-bit value, selectors 236, 237, 238, 239 and an operation unit 250 for outputting values stored in the decoder 220 and 221 or values obtained by inverting the values, per bit, stored in the decoder 220 and 221 when a target saturation operation value is over a saturated value detected by using selectors 234, 235 and operation units 226 and 227.
