摘要： An apparatus is described that comprises a data processing unit and at least one coprocessor. The data processing unit comprises a register file having registers, a memory, a plurality of execution units, a coprocessor interface for coupling the at least one coprocessor with the data processing unit, and a pipeline configuration for processing instructions having a fetch stage for fetching an instruction from the memory, a decode stage for decoding an operational code from the instruction, an execution stage for activating one of the execution units, and a write-back stage for God writing back from the execution unit. The data processing unit comprises read-and write-lines coupling the register file with the coprocessor for exchanging operands, at least one control line indicating that the coprocessor is busy, and a plurality of control lines from the decode stage for controlling the coprocessor which are operated upon detection of a coprocessor instruction. The coprocessor is using the registers from the register file during execution of the coprocessor instruction. The coprocessor comprises a decode unit for decoding the coprocessor instruction and a plurality of coprocessor execution units that share the decode unit, the decode unit selects one of the coprocessor execution units upon the coprocessor instruction, and the selected one of the coprocessor execution units performs the coprocessor instruction.
