Method, apparatus and instructions for parallel data conversions

A system comprising:

• at least one reduced instruction set computer (RISC) processor;
• a system memory to store instructions to be processed by the RISC processor;
• a memory controller to couple the RISC processor to the system memory over a system memory bus;
• and
• a network interface to couple the RISC processor to a network;
• the RISC processor comprising:
• a register file, within the RISC processor, including a first packed data register and a second packed data register;
• a register renamer within the RISC processor;
• a decoder, within the RISC processor, to decode the instructions, the instructions to include a first instruction;
• a scheduler, within the RISC processor, to queue operations that correspond to the instructions for execution;
• and
• execution logic, within the RISC processor, coupled to the decoder, the register renamer, and the scheduler, the execution logic to perform out-of-order execution of at least some of the instructions;
• wherein, responsive to a decode of the first instruction by the decoder, the execution logic is to convert a first plurality of packed signed data elements to be stored in the first packed data register to a second plurality of packed unsigned data elements in the second packed data register, one or more of the second plurality of packed unsigned data elements to be saturated;
• the first plurality of packed signed data elements to include floating point data elements and the second plurality of packed unsigned data elements to include integer data elements;
• at least one of the first plurality of packed signed data elements to have a first number of bits, at least one of the second plurality of packed unsigned data elements to have a second number of bits, wherein the second number of bits is one half the first number of bits.
