EISA System Introduction
Extended Industry Standard Architecture (EISA) is a high performance
32-bit architecture based upon the Industry Standard Architecture
(ISA) (PC AT). The wide acceptance of the 32-bit 386 microprocessor
family has led to this interest in extending ISA to 32-bits. EISA's
advanced capabilities and 32-bit architecture can unleash the full
potential of the 386 and i486 CPUs.
The EISA consortium has defined the EISA bus in response to the demand
for a 32-bit high performance ISA compatible system. The open industry
standard allows for industry wide participation, compatibility, and
differentiation.
EISA brings advances in performance and convenience to the user. It
provides 32-bit memory addressing and data transfers for CPU, DMA and
bus masters allowing 33 Mbyte/second transfer rate for DMA and bus
masters on the EISA bus. EISA provides a specification for
auto-configuration of add-in cards that will eliminate the need for
jumpers and switches on EISA cards. Interrupts are shareable and
programmable. Figure 1 and 2 [see datasheet] show the types of busses
in an EISA system. A new bus-arbitration makes possible a new
generation of intelligent bus master add-in cards that bring advanced
applications to PCs.
Since the EISA system is 100% compatible with the ISA 8-bit and 16-bit
expansion boards and software, ISA cards can be plugged into the EISA
connector slots. The EISA slots can be defined as ISA or EISA for ease
of compatibility during configuration. The EISA connector is a
superset of the ISA connector maintaining full compatibility with ISA
expansion cards and software. Simultaneous use of EISA and ISA add-in
boards is available with automatic system and expansion board
configuration.
82350 EISA Chip Set Highlights
The Intel 82350 EISA chip set is the industry's first 100% EISA/ISA
compatible chip set. The 82350 EISA chip set supports the 33 MHz and
25 MHz 386 CPU or i486 CPU, 82385 Cache Controller, and optional 80387
numerics coprocessor. The EISA chip set includes three chips:
82352DT EISA Bus Buffers (EBB) (Optional)
82357 Integrated System Peripheral (ISP)
82358 EISA Bus Controller (EBC)
Information on the 82352DT EBB device is located in a separate data
sheet.
The ISP performs the DMA functions of the system and is fully
compatible with ISA functions. It integrates seven 32-bit DMA chan-
nels, five 16-bit timer/ counters, two eight channel interrupt
controllers, and provides for multiple NMI control and generation. It
provides refresh address generation and keeps track of pending refresh
requests when the bus is unavailable. The ISP supports multiple EISA
bus masters while offering intelligent system arbiter services which
grant the bus on a rotational basis.
The EBC is the EISA "engine". It is an intelligent bus controller that
controls 8, 16 and 32-bit bus masters and slaves. It provides the
state machine interface to Host, ISA and EISA busses and other IC's in
the chip set. It offers a simple interface to the 386/i486 CPU and
EISA bus. The EBC services as a bridge between the EISA and ISA
devices. Data bus size mismatches are handled automatically by the EBC
(including byte assembly and disassembly). It also guarantees cache
operation on the Host, EISA, and ISA busses.
More information on EBC and ISP devices can be found in the data
sheets in this document.
The 82355 Bus Master Interface Chip (BMIC) is a new device for add-in
cards that takes advantage of the EISA bus master capab-
ilities. Information on the 82355 BMIC is located in a separate data-
sheet.
