Abstract
PURPOSE: To enable to reduce the processing time for the return from the interrupt or for the interrupt, by providing the control stack in CPU of one chip.
CONSTITUTION: The control stack 13 is placed in the one chip CPU 4, and the stack 13 provides the area able to store the internal state information and stores the internal state information to perform interrupt processing and high speed processing is made. In operating at the CPU level, if the interrupt of the IO level 4 is taken place, in the first machine cycle MC, the content of the micro program counter 8 is stored in the original MPC area for the IO level 4 of the stack 13 via the operation unit 15. At the second MC, the content of the processor state register 9 and the control register 10 is shunted to the original PCR and CTL area for the IO level 4 of the stack 13, and at the third MC, the content stored in the new MPC area is stored in the counter 8. At the fourth MC, the content stored in the new PCR and CTL is respectively stored in the registers 9 and 10
