****82357 Integrated System Peripheral (ISP)
The 82357 is a multi-function support peripheral that is designed to
work in conjunction with the 82358 or 82358DT EISA Bus Controller to
provide most of the system functions necessary in EISA specific
applications.
The 82357 is comprised of several computer system functions that are
typically found in separate LSI and VLSI components. These include: a
high performance seven-channel programmable DMA Controller; an
arbitration scheme that allows efficient bus sharing among multiple
EISA masters, the host CPU, and DMA devices; a 16 level programmable
interrupt controller which provides level-or-edge triggered interrupt
capability on a channel-by-channel basis; non-maskable interrupt logic
for multiple NMI control and generation; refresh address generation
and control; and five counter/timers which provide a system timer
interrupt, diskette time-out, DRAM refresh requests, and other system
timing operations.
The DMA controller on the 82357 provides the timing control signals
necessary to support a DMA data transfer rate of 33 Mbytes/sec. The
DMA controller includes full function 32-bit addressability with
control signal support for the transfer of data between devices of
different data path widths using a single channel. Each channel
functions independently in several modes.
1.0 ISP SYSTEM INTERFACE ILLUSTRATION
The ISP connects to the Host bus, EISA bus, X bus and EBC (Bus
Controller). These connections are illustrated in Figure 1-1 [see
datasheet].
2.0 FUNCTIONAL OVERVIEW
The following is a brief discussion of the functionality and features
of the 82357. The DMA Controller, Arbiter, Interrupt controller,
NMI's, and Timer/Counters each have a corresponding detailed section
later in this data sheet.
