S5933 Architecture
The block diagram in figure 1 above shows the
major functional elements within the S5933. The
S5933 provides three physical bus interfaces: the
PCI Local bus, the user local bus referred to as the
Add-On Local bus and the optional serial and byte-
wide non-volatile memory buses. Data movement
between buses can take place through mailbox reg-
isters or the FIFO data channel, or a user can define
and enable one or more of the four Pass-Thru data
channels. S5933 Bus Master or DMA data transfers
to and from the PCI Local bus are performed
through the FIFO data channel under either Host or
Add-On software control or Add-On hardware con-
trol using dedicated S5933 signal pins.
The S5933 signal pins are shown in Figure 2 right.
The PCI Local Bus signals are detailed on the left
side; Add-On Local Bus signal are detailed on the
right side. All additional S5933 device control sig-
nals are shown on the lower right side.
The S5933 supports a two wire serial nvRAM bus
and a byte-wide EPROM/FLASH bus. This allows
the designer to customize the S5933 configuration
by loading setup information on system power-up.

S5933 Register Architecture
Figure 2
Control and configuration of the Add-On Local bus, and the MatchMaker itself, is performed through three primary
groups of registers. These groups consist of PCI Configuration Registers, PCI Operation Registers and Add-On Oper-
ation Registers. All these registers are user configurable through their associated bus or from an external non-volatile
memory device. This section will provide a brief overview of each of these register groups and the optional non-vola-
tile interface.
