Comparison with the MPC7400, MPC7410, MPC7450, MPC7451, and MPC7441
Power and thermal management
— 1.3-V processor core
— The following three power-saving modes are available to the system:
– Nap—Instruction fetching is halted. Only those clocks for the time base, decrementer, and
JTAG logic remain running. The part goes into the doze state to snoop memory operations
on the bus and then back to nap using a QREQ/QACK processor-system handshake
protocol.
– Sleep—Power consumption is further reduced by disabling bus snooping, leaving only the
PLL in a locked and running state. All internal functional units are disabled.
– Deep sleep—When the part is in the sleep state, the system can disable the PLL. The
system can then disable the SYSCLK source for greater system power savings. Power-on
reset procedures for restarting and relocking the PLL must be followed on exiting the deep
sleep state.
— Thermal management facility provides software-controllable thermal management. Thermal
management is performed through the use of three supervisor-level registers and an
MPC7455-specific thermal management exception.
— Instruction cache throttling provides control of instruction fetching to limit power
consumption
Performance monitor can be used to help debug system designs and improve software efficiency
In-system testability and debugging features through JTAG boundary-scan capability
Testability
— LSSD scan design
— IEEE 1149.1 JTAG interface
— Array built-in self test (ABIST)—factory test only
Reliability and serviceability
— Parity checking on system bus and L3 cache bus
— Parity checking on the L2 and L3 cache tag arrays
1.3
Comparison with the MPC7400, MPC7410,
MPC7450, MPC7451, and MPC7441
Table 1 compares the key features of the MPC7455 with the key features of the earlier MPC7400,
MPC7410, 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 MPC7455 is extended
(compared to the MPC7400), while maintaining the same level of performance as measured by the number
of instructions executed per cycle (IPC).
