摘要：
A method for controlling the execution of a microprocessor to cause it to execute a NOP instruction for a programmable number of sequential cycles. A NOP instruction is provided, that includes a predetermined OP code field identifying the NOP instruction as a programmably multiple NOP instruction. A predetermined count field is provided, representing the number of sequential cycles in which a NOP operation is to be performed by said microprocessor. The NOP instruction OP code field is read, as is the NOP instruction count field. In response thereto, a NOP operation is performed for the number of sequential cycles represented by said NOP instruction count field.
