Features and Function

These sections describe the base adapter and the mezzanine card.

IBM ARTIC960RxD PCI Adapter—Base Adapter

The base adapter provides high-function control of I/O operations and serves to off-load input/output tasks from the system microprocessor. The base adapter has the following standard features:

ŸAn Intel 80960RD processor (clock-doubled RP) running at up to 33 MHz

(depends on the PCI clock on the system bus)

Ÿ On-board		memory,	which is	available only to	the processor on the base adapter
and	cannot be accessed			through the system	bus.
–	4 MB	extended-data-output (EDO) dynamic random-access memory (DRAM)
–	Flash	read-only	memory	(ROM)

Ÿ A 32-bit system-bus PCI interface

ŸTwo Texas Instruments TMS320C6201 digital signal processors (DSPs),

operating at a clock cycle of 200 MHz. Each DSP has 512 KB of synchronous-burst static random-access memory (SBSRAM) and can process up to 1 600 000 000 instructions per second.

Ÿ A PLX	technology	9080,	which provides	the 80960RD	processor with access to
the	SC4000s and	DSPs	using memory-mapped	I/O and	DMA access.

ŸTwo VLSI VP06967 SC4000 chips, which provide an interface to the H.100 connector. One chip provides an interface between the DSPs and the H.100

connector; the other provides an interface between the mezzanine card and the H.100 connector.

Ÿ An ECTF H.100 connector operating in SC-bus compatible mode

ŸPMC connectors, which support attaching any mezzanine card with a PCI mezzanine card (PMC) interface
