The MPC755 is targeted for low-cost, low-power systems and supports the following power management features—doze, nap, sleep, and dynamic power management. The MPC755 consists of a processor core and an internal L2 tag combined with a dedicated L2 cache interface and a 60x bus. The MPC745 is identical to the MPC755 except it does not support the L2 cache interface.
Branch processing unit
— Four instructions fetched per clock
— One branch processed per cycle (plus resolving two speculations)
— Up to one speculative stream in execution, one additional speculative stream in fetch
— 512-entry branch history table (BHT) for dynamic prediction
— 64-entry, four-way set-associative branch target instruction cache (BTIC) for eliminating
branch delay slots
Dispatch unit
— Full hardware detection of dependencies (resolved in the execution units)
— Dispatch two instructions to six independent units (system, branch, load/store, fixed-point
unit 1, fixed-point unit 2, floating-point)
— Serialization control (predispatch, postdispatch, execution serialization)
Decode
— Register file access
— Forwarding control
— Partial instruction decode
Completion
— Six-entry completion buffer
— Instruction tracking and peak completion of two instructions per cycle
— Completion of instructions in program order while supporting out-of-order instruction
execution, completion serialization, and all instruction flow changes
Fixed point units (FXUs) that share 32 GPRs for integer operands
— Fixed Point Unit 1 (FXU1)—multiply, divide, shift, rotate, arithmetic, logical
— Fixed Point Unit 2 (FXU2)—shift, rotate, arithmetic, logical
— Single-cycle arithmetic, shifts, rotates, logical
— Multiply and divide support (multi-cycle)
— Early out multiply
