MULTIMEDIA COPROCESSOR CONTROL MECHANISM INCLUDING ALIGNMENT OR BROADCAST INSTRUCTIONS
摘要
<p>A processor-based system (22) may include a main processor (24) and a coprocessor (26). The coprocessor (26) handles instructions that include opcodes specifying a data processing operation to be performed by the coprocessor (26) and a coprocessor identification field for identifying a target coprocessor for coprocessor instructions. Two bits indicate one of four data sizes including a byte (8 bits), a half word (16 bits), a word (32 bits), and a double word (64 bits). Two other bits indicate a saturation type.</p>
