Abstract
A processor-based system may include a main processor and a coprocessor. The coprocessor handles instructions that include opcodes specifying a data processing operation to be performed by the coprocessor 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. A source register in the main processor and a destination register is in the coprocessor, those registers including data elements. The coprocessor instruction includes an opcode specifying a data processing operation to be performed by the coprocessor and a coprocessor identification field for identifying a target coprocessor for the coprocessor instruction, the instruction to broadcast a data element from said source register to said destination register.
