摘要：
An apparatus for implementing branch intensive algorithms is disclosed. The apparatus includes a processor containing a plurality of ALUs and a plurality of result registers. Each result register has a guard input which allows the ALU to write a result to the register upon receipt of a selection signal at the guard input. A lookup table is dynamically programmed with logic to implement an upcoming branching portion of program code. Upon evaluation of the branch conditions of the branching portion of code, the lookup table outputs a selection signal for writing the correct results of the branching portion of code based on the evaluation of the branch condition statements and the truth table programmed into the lookup table to the result register.
