Parallel Maximum InstructionParallel Maximum Instructionpmax
Instruction Type I
Format
(qp) pmax1.u r1 = r2, r3 one_byte_form
(qp) pmax2 r1 = r2, r3 two_byte_form
Description
The maximum of the two source operands is placed in the result register. In the one_byte_form, each unsigned 8-bit element of GR r2 is compared with the corresponding unsigned 8-bit element of GR r3 and the greater of the two is placed in the corresponding 8-bit element of GR r1. In the two_byte_form, each signed 16-bit element of GR r2 is compared with the corresponding signed 16-bit element of GR r3 and the greater of the two is placed in the corresponding 16-bit element of GR r1.
