PCI Bus Interface
The Z10, Z13, Z25, and V25 graphics accelerators are 32-bit PCI peripherals.
PCI-Compatible Bus Interface
The PCI direct memory access (PCIDMA) application-specific integrated circuit (ASIC)
provides the PCI-compatible bus interface for these accelerators, including bus mastership
capability. This interface provides a high-speed, industry-standard connection between the
host processor and the graphics accelerator.
High-Speed DMA Engine
The Rasterization Accelerator uses a high-speed DMA engine to accelerate PCI bus data
transfers. The DMA engine transfers data in bursts without intervention from the host
processor. These unattended transfers free the host processor from transferring massive
amounts of graphics data over the PCI bus.
