Branch instruction process method, count and link branch instruction processor method, and multiple branch instruction process system

摘要

the majority of the branch (multiple branches) to count and link registers (count and link register) by that name to the command register (rename registers) can not be limited at the same time, in order to allow the processing status of the branch and the branch instruction in the program. a system and method for the service. according to the method. the system is simple, and the register (look - -. ahead register) on each connection system. the count register (architected count system. register) and the link register (architected link register) etc..branch and link register of the change will make the branch instruction or not and if the system account or a register in the first register information to be copied. the first register in the information pending branch, and we see the register (shadow register) stored in the branch, pending the result of the prediction is wrong, we register the recovery.
