Abstract

PURPOSE: To avoid the waiting time produced for the judgement of branch condition, by reading out the index register, base register, and branch condition indicating register in the same timing.
CONSTITUTION: When the branch instruction 7 is read out, the content of the index register designation section X2 is set to the address register 2-1, the content of the base register designating section R1 is to the address register 3-1, and the content of the branch condition indicating register designation section R1 is to the address register 2-0 respectively. Further, similarly in the next cycle, they are respectively set to the registers 4-1, 5-1 and 4-0, and if the branch is successful, the content of the branch condition indication register shows other than 1.
