CHAPTER 2 SYSTEM CONTROLLERS

This chapter describes the major structure of the

PC104-386L-2M CPU board. The following topics are

covered:

$

Microprocessor

$

DMA Controller

$

Keyboard Controller

$

Interrupt Controller

$

Serial Ports

$

Parallel Ports

2.1 MICROPROCESSOR

The

PC104-386L-2M uses the ALI M6117 CPU; it is designed to perform systems like Intel’s 386SX system

with deep green features.

The 386SX core is the same as M1386SX of Acer Labs. Inc. and 100% object code
compatible with the Intel 386SX microprocessor. System manufacturers can provide 386
CPU based systems optimized for both cost and size. Instruction pipelining and high bus
bandwidth ensure short average instruction execution time and high system throughput.
Furthermore, it can keep the state internally from charge leakage while external clock to the
core is stopped without storing the data in registers. The power consumption here is almost
zero until the clock stops. The internal structure of this core is 32-bit data and address bus with
very low supply current. Real mode as well as Protected mode are available and can run MS-
DOS /MS-Windows.

2.2 DMA CONTROLLER

The equivalent of two 8237A DMA controllers are implemented in the

PC104-386L-2M board.Each

controller is a four-channel DMA device that will generate the memory addresses and control
signals necessary to transfer information directly between a peripheral device and memory. This
allows high speeding information transfer with less CPU intervention. The two DMA controllers
are internally cascaded to provide four DMA channels for transfers to 8-bit peripherals (DMA1)
and three channels for transfers to 16-bit peripherals (DMA2). DMA2 channel 0 provides the
cascade interconnection between the two DMA devices, thereby maintaining IBM PC/AT
compatibility.

The following is the system information of DMA channels:

DMA Controller 1

DMA Controller 2

Channel 0: Spare

Channel 4: Cascade for controller 1

Channel 1: Reserved for IBM SDLC Channel 5: Spare
Channel 2: Diskette adapter

Channel 6: Spare

Channel 3: Spare

Channel 7: Spare
