**82C822 PCIB (VLB-to-PCI bridge) c:94
***Notes:...
***Info:
OPTi's 82C822 VESA local bus to PCI Bridge (PCIB) chip is a high
integration 208-pin PQFP device designed to work with VESA VL bus
compatible core logic chipsets. The 82C822 PCIB provides interface to
the high performance PCI bus and is fully compliant to the PCI Version
2.0 specification. The 82C822 requires no glue logic to implement the
PCI bus interface and hence it allows designers to have a highly
integrated motherboard with both VESA local bus and PCI local bus
support. The PCIB chip offers premium performance and flexibility for
VESA VL-based desktop systems running up to 50MHz. The 82C822 PCIB can
be used with OPTi's 82C802G core logic and 82C602 buffer chipsets to
build a low cost and power efficient 486-based desktop solution. It
also works with OPTi 82C546/547 chipset to build a high performance
PCI/VL solution based on the Intel P54C processor.
The 82C822 PCIB provides all of the control, address and data paths to
access the PCI bus from the VESA Local bus (VL bus). The 82C822
provides a complete solution including data buffering, latching,
steering, arbitration, DMA and master functions between the 32-bit VL
bus and the 32-bit PCI bus.
The PCIB works seamlessly with the motherboard chipset bus arbiter to
handle all requests of the host CPU and PCI bus masters, DMA masters,
I/O relocation and refresh. Extensive register and timer support are
designed into the 82C822 to implement the PCI specification.
The 82C822 is a true VESA to PCI bridge. It has the highest priority
on CPU accesses after cache and system memory. It generates LDEV#
automatically and then compares the addresses with its internal
registers to determine whether the current cycle is a PCI cycle. When
a cycle is identified as PCI cycle, the 82C822 will take over the
cycle and then return RDY# to the CPU. If not, the 82C822 will give up
the cycle to the local device or, in the case of an ISA slave,
generate a BOFF# cycle to the CPU. This action will abort the cycle
and allow the CPU to rerun the cycle.
The 82C822 includes registers to determine shadow memory space, hole
locations and sizes to allow the 82C822 to determine which memory
space should be local and which is located on the ISA bus. Upon access
to memory, the 82C822 can determine whether or not the cycle is a PCI
access by comparing the cycle with its internal registers.
