摘要:
In a microprocessor system, a program counter circuit generates a program counter value that represents a retrieved instruction and that includes a more significant portion, a less significant portion, and a carry signal for use in determining a next program counter value. An execute program counter circuit generates an execute program counter value from the less significant program counter value and from the carry signal. The execute program counter value represents a program counter value of an executed instruction.
