18 / 85 page 128-BIT 3D MULTIMEDIA ACCELERATOR RIVA128ZX 18/85 Figure 6. Single address - no delay by master Figure 7 shows the RIVA128ZX enqueuing 4 requests, where the first request is delayed by the maximum 2 cycles allowed. START is indicated on clock 2, but the RIVA128ZX does not assert AGPPIPE# until clock 4. Note that PCIREQ# remains asserted on clock 6 to indicate that the current request is not the last one. When PCIREQ# is deasserted on clock 7 with AGPPIPE# still asserted this indicates that the current address is the last one to be enqueued during this transaction. AGPPIPE# must be deasserted on the next clock when PCIREQ# is sampled as deasserted. If the RIVA128ZX wants to enqueue more requests dur- ing this bus operation, it continues asserting AGPPIPE# until all of its requests are enqueued or until it has filled all the available request slots provided by the target. Figure 7. Multiple addresses enqueued, maximum delay by RIVA128ZX 2X Data Transfers 2X data transfers are similar to 1X transfers except that an entire 8 bytes are transferred during a single PCICLK period. This requires that two 4 byte pieces of data are transferred across PCIAD[31:0] for each CLK period. A read data transfer is described followed by a write transfer.
