Command Processor Stores all GPU state (debug?). Stores all GPU state (debug?). Receives data from AGP and sends it to the Memory Controller. Receives data from AGP and sends it to the Memory Controller. Receives state changes and sends them to the GPU units. Receives state changes and sends them to the GPU units. Receives commands and issues them to the GPU units. Receives commands and issues them to the GPU units.

Memory Controller Access to memory modules => Signal. Access to memory modules => Signal. To decide: number of transactions in process at the same time. To decide: number of transactions in process at the same time. Currently only one transaction at a time. Currently only one transaction at a time. Support multiple modules and multiple banks per module. Support multiple modules and multiple banks per module.

Streamer Two modes: Two modes: Streaming mode. Streaming mode. Index based streaming mode. Index based streaming mode. Streaming mode: Streaming mode: 1) get data for each active attribute. 1) get data for each active attribute. 2) store vertex input data in the FIFO. 2) store vertex input data in the FIFO. 3) send vertex input to a vertex shader. 3) send vertex input to a vertex shader. 4) repeat until end. 4) repeat until end.

Streamer Index based streaming mode: Index based streaming mode: 1) get index data. 1) get index data. 2) get vertex attribute data using index information. 2) get vertex attribute data using index information. 3) store vertex input in FIFO. 3) store vertex input in FIFO. 4) send vertex input to vertex shader. 4) send vertex input to vertex shader. 5) repeat until end. 5) repeat until end.

Streamer Accessing to attribute data in stream mode: Accessing to attribute data in stream mode: Direct access. Direct access. Double buffer (pipelined: read first, process first/read second, read first/process second). Double buffer (pipelined: read first, process first/read second, read first/process second). Accessing to attribute data in index mode: Accessing to attribute data in index mode: Attribute buffer could work like a cache? Attribute buffer could work like a cache? Number of attributes per ‘cache line’. Number of attributes per ‘cache line’. Replacement policy. Replacement policy.
