General Purpose PCI Interfacing

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing

system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places

them closer to the system’s processor bus, providing faster data transfer between the processor and peripherals. The PCI

Local bus also addresses the industry’s need for a standard that is not directly dependent on the speed, size and type of

processor bus. It represents the first microprocessor independent bus offering performance more than adequate for the

most demanding applications, such as full-motion video.

Applied Micro Circuits Corporation (AMCC), the premier supplier of single chip solutions, has developed and pro-

duced the S5933 to solve the problem of interfacing applications to the PCI Local bus. The S5933, or ‘Matchmaker’, is

a powerful and flexible PCI controller supporting several levels of interface sophistication. At the lowest level, it can

serve simply as a PCI bus Target with modest transfer requirements. For high-performance applications, the S5933 can

become a Bus Master to attain the PCI Local bus peak transfer capability of 132 MBytes/sec.

The MatchMaker is an off-the-shelf, low-cost, standard product, which is PCI 2.1 compliant. And, since AMCC is a

member of the PCI Special Interest Group, the S5933 has been tested in "compliance workshops" along with other man-

ufacturer's PCI systems, chip sets and BIOSs. This removes the burden of compliance testing from the designer and thus

significantly reduces development time. Utilizing the S5933 allows the designer to focus on the actual application, not

debugging the PCI interface.

The MatchMaker allows special direct data accessing between the PCI bus and the user application through implemen-

tation of four definable Pass-Thru data channels. Each data channel is implemented by defining a Host memory segment

size and 8/16/32-bit user bus width. The addition of two 32 byte FIFOs, also used in S5933 Bus Mastering applications,

provides further versatility to data transfer capabilities. FIFO DMA transfers are supported using Address and Transfer

Count Registers. Four 32-bit Mailbox Registers coupled with a Status Register and extensive interrupt capabilities pro-

vide flexible user command or message transfers between the two buses. In addition, the S5933 also allows use of an

external serial, or byte-wide non-volatile memory to perform any pre-boot initialization requirements and to provide

custom expansion BIOS or POST code capability.
