Features

This section summarizes features of the MPC7448 implementation.
Major features of the MPC7448 are as follows:
High-performance, superscalar microprocessor
— Up to four instructions can be fetched from the instruction cache at a time.
— Up to three instructions plus a branch instruction can be dispatched to the issue queues at a
time.
— Up to 12 instructions can be in the instruction queue (IQ).
— Up to 16 instructions can be at some stage of execution simultaneously.
— Single-cycle execution for most instructions
— One instruction per clock cycle throughput for most instructions
— Seven-stage pipeline control
Eleven independent execution units and three register files
— Branch processing unit (BPU) features static and dynamic branch prediction
– 128-entry (32-set, four-way set-associative) branch target instruction cache (BTIC), a cache
of branch instructions that have been encountered in branch/loop code sequences. If a target
instruction is in the BTIC, it is fetched into the instruction queue a cycle sooner than it can
be made available from the instruction cache. Typically, a fetch that hits the BTIC provides
the first four instructions in the target stream.
– 2048-entry branch history table (BHT) with 2 bits per entry for four levels of
prediction—not taken, strongly not taken, taken, and strongly taken
– Up to three outstanding speculative branches
– Branch instructions that do not update the count register (CTR) or link register (LR) are
often removed from the instruction stream.
– Eight-entry link register stack to predict the target address of Branch Conditional to Link
Register (bclr) instructions
— Four integer units (IUs) that share 32 GPRs for integer operands
– Three identical IUs (IU1a, IU1b, and IU1c) can execute all integer instructions except
multiply, divide, and move to/from special-purpose register instructions.
– IU2 executes miscellaneous instructions, including the CR logical operations, integer
multiplication and division instructions, and move to/from special-purpose register
instructions.
— Five-stage FPU and 32-entry FPR file
– Fully IEEE Std. 754-1985–compliant FPU for both single- and double-precision
operations
– Supports non-IEEE mode for time-critical operations
– Hardware support for denormalized numbers
– Thirty-two 64-bit FPRs for single- or double-precision operands
