ABSTRACT:
In a microprocessor having conditional execution instructions, an execution halt circuit incorporated in an instruction decoder temporarily halts the execution of a current instruction according to the operation result of a preceding instruction in a program. When a conditional execution decision circuit judges to cancel the execution of the preceding instruction, the conditional execution decision circuit cancels a start signal indicating to initiate the operation of the preceding instruction. Furthermore, the conditional execution decision section or circuit judges whether a conditional data stored in a general purpose flag is equal to a condition stored in an execution conditional field, and bypass control sections control use of bypasses and data passes for data transfer operation according to the decision result of the conditional execution decision section.
