* IBM '[http://en.wikipedia.org/wiki/Broadway_%28microprocessor%29 Broadway]' 90 nm based on IBM's Power architecture.
−
*Runs at a speed of 729 MHz. Maximum Bandwidth is 1.9 GB/s.
−
*Bus to main memory: 243 MHz, 64 bits (maximum bandwidth: 1.9 GB/s)
−
*32 KB 8-way set-associative L1 instruction cache
−
*32 KB 8-way set-associative L1 data cache (can set up 16-kilobyte data scratch pad)
−
*Superscalar microprocessor with six execution units (floating-point unit, branching unit, system register unit, load/store unit, two integer units)
−
*DMA unit (15-entry DMA request queue) used by 16-kilobyte data scratch pad
−
*Write-gather buffer for writing graphics command lists to the graphics chip
−
*Onboard 256-kilobyte 2-way set-associative L2 integrated cache
−
*Two, 32-bit integer units (IU)
−
*One floating point unit (FPU) (supports single precision (32-bit) and double precision (64-bit))
−
*The FPU supports paired single floating point (FP/PS)
−
*The FPU supports paired single multiply add (ps_madd). Most FP/PS instructions can be issued in each cycle and completed in three cycles.
−
*Fixed-point to floating-point conversion can be performed at the same time as FPU register load and store, with no loss in performance.
−
*The branch unit supports static branch prediction and dynamic branch prediction.
−
*When an instruction is stalled on data, the next instruction can be issued and executed. All instructions maintain program logic and will complete in the correct program order.
−
*Supports three L2 cache fetch modes: 32-Byte, 64-Byte, and 128-Byte.
−
*Supports these bus pipeline depth levels: level 2, level 3, and level 4.
−
Reference Information: Broadway is upward compatible with Nintendo GameCube’s CPU (Gekko).
−
−
*Broadway CPU version is 87102, Gekko is 83410. Source: http://forum.wiibrew.org/viewtopic.php?t=210
−
*Information about its [[Broadway/Registers|registers]] is available
