The Wii Hardware

- Nintendo Wii’s ‘Broadway’ CPU operates at 729MHZ with a maximum bandwith of 1.9gbyte/sec.
- Nintendo Wii’s ‘HollyWood’ GPU is clocked at 243MHZ, the internal memory of it includes 3mb of embedded graphics memory and 24megabytes of high speed main memory.
- 64megabytes of GDDR3 (MEM2) as the external main memory. Just like the internal memory, it can be accessed from the CPU and GPU with a maximum bandwidth of 4gbytes/sec and can also store programs in the MEM2.
- The GPU of the Wii is identical to the GC’s but it is on average 1.5X faster.

Broadway CPU

Broadway is Wii's CPU. Broadway functionality and specifications are as follows.

• Operating speed: 729 MHz
• Bus to main memory: 243 MHz, 64 bits (maximum bandwidth: 1.9 gigabytes/sec)
• 32-kilobyte 8-way set-associative L1 instruction cache
• 32-kilobyte 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 regis
ter 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).


Hollywood GPU

Hollywood is a system LSI composed of a GPU and internal main memory (MEM1). Hollywood is clocked at 243 MHz. Its internal memory consists of 3 megabytes of embedded graphics memory and 24 megabytes of high speed main memory.

Hollywood includes the following.
• Graphics processing unit (with 3 megabytes of eDRAM)
• Audio DSP
• I/O Bridge
• 24 megabytes of internal main memory
• Internal main memory operates at 486 MHz.
Maximum bandwidth between Hollywood and internal main memory: 3.9 gigabytes per second
• Possible to locate a program here
Reference Information: Hollywood is similar to Nintendo GameCube’s Flipper and Splash components.

Revolution runs on an extension of the Gekko and Flipper architectures that powered GameCube, which is why studios who worked on GCN will have no problem making the transition to the new machine, they say. IBM's "Broadway" CPU is clocked at 729MHz, according to updated Nintendo documentation. By comparison, GameCube's Gekko CPU ran at 485MHz.

Revolution's ATI-provided "Hollywood" GPU clocks in at 243MHz. By comparison, GameCube's GPU ran at 162MHz.

Two questions:

a. Can the same emulator that emulates the Gamecube emulate the Wii like the Virtual Boy emulator?

b. Do you think my current CPU(Conroe 6600) be able to emulate the Wii perfectly or will the demands of the "Future Wii emulater" need more power?
