Title: Two-step address comparing circuit
Inventor: MOGI HITOSHI
IPC: G06F11/28
Filed: 1981-06-24
Abstract: PURPOSE:To stop the operation of a CPU in an optional address based on an actual processing course, by registering preliminarily first and second addresses in the processing course of a program. CONSTITUTION:Contents of an address register REG0 and the first address of an address comparison register REG1 are compared with each other in a comparator COMP; and when they coincide with each other, the output is generated in an AND gate AND4. This output resets a flip-flop FF3 through an AND gate AND6 and an inverter INV to invert outputs Q3 and Q3' of the flip-flop FF3. Since outputs Q3 and Q3' are 0 and 1 respectively hereafter, AND gates AND1 and AND4 are closed, and AND gates AND2 and AND5 are opened instead. As a result, the comparator COMP compares contents of the register REG0 and the second address of an address comparison register REG2. When they coincide with each other, the output of the comparator COMP becomes an address stop signal through gates AND3, AND5, AND8 and OR2.
