    Hawk PCI Host Bridge & Multi-Processor Interrupt Controller Functional Description Architectural Overview A functional block diagram of the Hawk’s PHB is shown in Figure 2-1. The PHB control logic is subdivided into the following functions: PCI slave, PCI master, PPC slave, and PPC master. The PHB data path logic is subdivided into the following functions: PCI FIFO, PPC FIFO, PCI Input, PPC Input, PCI Output, and PPC Output.

    The PHB will map either PCI memory space or PCI I/O space into PPC address space using four programmable map decoders. These decoders provide windows into the PCI bus from the PPC bus.

  • Page 66

    Hawk PCI Host Bridge & Multi-Processor Interrupt Controller AACK_ and TA_ allows the PPC Slave to assert a retry to the processor in the event that the transaction is unable to complete on the PCI side. It should be noted that any transaction that crosses a PCI word boundary could be disrupted after only having a portion of the data transferred.

    A 46-bit by 4 entry FIFO is used to hold command information being passed between the PPC Slave and the PCI Master. If write posting has been enabled, then maximum number of transactions that may be posted is http://www.motorola.com/computer/literature Artisan Technology Group - Quality Instrumentation ...

    Hawk PCI Host Bridge & Multi-Processor Interrupt Controller limited by the abilities of either the data FIFO or the command FIFO. For example, two burst transactions would make the data FIFO the limiting factor for write posting. Four single beat transactions would make the command FIFO be the limiting factor.

    PCI Slave is continuously stalling during write posted transactions, then further tuning might be needed. This can be accomplished by changing the WXFT (Write Any FIFO Threshold) field within the http://www.motorola.com/computer/literature 2-11 Artisan Technology Group - Quality Instrumentation ...
