Essential Knowledge Summary for Embedded C Programming

Essential Knowledge Summary for Embedded C Programming

1. A pipeline can achieve maximum efficiency only when it is filled with instructions, meaning that one instruction is executed per clock cycle (this refers only to single-cycle instructions). If a jump occurs in the program, the pipeline will be cleared, and it will take several clock cycles to refill the pipeline. Therefore, minimizing the … Read more
