Abstract
PURPOSE: To realize a high-speed action of the shunt release as well as reduce greatly the overhead time in case the number of general registers increases, by providing the shunt control register which designates the general register to be shunted.
CONSTITUTION: Shunt control register 1 is provided. When the general register GR to be shunted is designated by one order in the program, the contents is stored in register 1 via signal line 11. Then shunt operation start signal 51 is applied to logic circuit 5 when the order indicating the shunt action of the GR emerges in the program. And then the bit position information of register 1 corresponding to GR4 (GR0WGR7) is selected by output signal 31 and through multiplexer 2 to be read by signal 21. At this moment, if signal 21 is "1", GR0 shows the necessity for shunt to make main memory 7 shunt GR0. This shunt operation is continued until counter 3 finishes the designation for all GRs. After this, the release order is designated through the program, and release operation start signal 52 is applied to circuit 5.
