Technical data of product parameters

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, OCAHG492838402
PPC Input, PCI Output, and PPC Output. Address decoding is handled in
the PCI Decode and PPC Decode blocks. The control register logic is
contained in the PCI Registers and PPC Registers blocks. The clock
phasing and reset control logic is contained within the PPC/PCI Clock
block.
The FIFO structure implemented within PHB has been selected to allow
independent data transfer operations to occur between PCI bound
transactions and PPC bound transactions. The PCI FIFO is used to support OCAHG492838402
PPC bound transactions, while the PPC FIFO is used to support PCI bound
transactions. Each FIFO supports a command path and a data path. The
data path portion of each FIFO incorporates a multiplexer to allow
selection between write data and read data, as well as logic to handle the OCAHG492838402
PPC/PCI endian function.
All PPC originated PCI bound transactions utilize the PPC Slave and PCI
Master functions for maintaining bus tracking and control. During both
write and read transactions, the PPC Slave will place command
information into the PPC FIFO. The PCI Master will draw this command
information from the PPC FIFO when it is ready to process the transaction.
During write transactions, write data is captured from the PPC60x bus
within the PPC Input block. This data is fed into the PPC FIFO.The PCI
Output block removes the data from the FIFO and presents it to the PCI OCAHG492838402
bus. During read transactions, read data is captured from the PCI bus
within the PCI Input block. From there, the data is fed into the PPC FIFO.
The PPC Output block removes the data from the FIFO and presents it to
the PPC60x bus.
