WebConditional execution is a good choice in implementation of many auxiliary or bit-twiddling routines, such as sorting, list or tree manipulation, number to string conversion, sqrt or long division. We could add UART drivers and extracting bit fields in routers. Those have a high branch to non-branch ratio with somewhat high unpredictability too. Webthe pipeline recognizes branch instructions and performs branch prediction using a BHT. If the branch is predicted to be taken, it forwards the decoded target of the branch ... page. In the B stage (Branch Address Calc/Begin Decode), a conditional branch instruction (BEQZ/BNEZ) looks up the BHT, but an unconditional jump does not. If a branch ...

WebBranch conditional instructions can be coded with the operations, a condition to be tested, and a prediction, as part of the instruction mnemonic rather than as numeric operands (the BO and BI operands). Table 4 shows the four general types of branch instructions. Simplified mnemonics are defined only for branch Branch instructions are used to implement control flow in program loops and conditionals (i.e., executing a particular sequence of instructions only if certain conditions are satisfied). A branch instruction can be either an unconditional branch , which always results in branching, or a conditional branch , which may or may not cause branching ...
