Comparison with the MPC7455, MPC7445, MPC7450,
MPC7451, and MPC7441
Table 1 compares the key features of the MPC7457 with the key features of the earlier MPC7455,
MPC7445, MPC7450, MPC7451, and MPC7441. To achieve a higher frequency, the number of logic
levels per cycle is reduced. Also, to achieve this higher frequency, the pipeline of the MPC7457 is
extended (compared to the MPC7400), while maintaining the same level of performance as measured by
the number of instructions executed per cycle (IPC).
