0.6 ORGANIZATION

This manual covers the following topics (see the Table of Contents for a detailed listing):

! Chapter 1, “Overview”, provides an overview of the system features and packing list. ! Chapter 2, “System Controller” describes the major structure. ! Chapter 3, “Setting Up the System”, describes how to adjust the jumper, and the connector’s settings. ! Chapter 4, “Installation”, describes setup procedures including information on the utility diskette. ! Chapter 5, “BIOS Console”, provides the BIOS options settings.

0.7 STATIC ELECTRICITY PRECAUTIONS

Before removing the board from its anti-static bag, read this section about static electricity precautions. Static electricity is a constant danger to computer systems. The charge that can build up in your body may be more than sufficient to damage integrated circuits on any PC board. It is, therefore, important to observe basic precautions whenever you use or handle computer components. Although areas with humid climates are much less prone to static build-up, it is always best to safeguard against accidents that may result in expensive repairs. The following measures should be sufficient to protect your equipment from static discharge:

• Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a grounded

wrist strap).

• When unpacking and handling the board or other system components, place all materials on an anti-static

surface.

• Be careful not to touch the components on the board, especially the “golden finger” connectors on the bottom

of the board.

2. SYSTEM CONTROLLER

This chapter describes the main structure of the AR-B1570 CPU board. The following topics are covered:

! Microprocessors ! DMA Controller

Keyboard Controller

! ! Interrupt Controller ! Serial Port

Parallel Port

2.1 MICROPROCESSOR

The AR-B1570 uses the NS GEODE GX1 CPU, it is an advanced 32-bit x86 compatible processor offering high performance, fully accelerated 2D graphics, a 64-synchronous DRAM controller and a PCI bus controller, all on a single chip. This latest generation of the MediaGX processor enables a new class of premium performance notebook/desktop, and IPC computer designs. The MediaGX MMX enhanced processor companion chips provide advanced video and audio functions and permit direct interface to memory. This high-performance 64-bit processor is x86 instruction set compatible and supports MMX technology. This processor is the latest member of the NS MediaGX family, offering high performance, fully accelerated 2D graphics, synchronous memory interface and a PCI bus controller, all on a single chip. As described in separate manuals, the CS5520 and the CS5530 I/O Companion chips fully enable the features of the MediaGX processor with MMX support. These features include full VGA and VESA video, 16-bit stereo sound, IDE interface, ISA interface, SMM power management, and AT compatibility logic. In addition, the newer CS5530 provides an Ultra DMA/33 interface, MPEG2 assist, and is AC97 Version 2.0 audio compliant. In addition to the advanced CPU features, the MediaGX processor integrates a host of functions, which are typically implemented with external components. A full-function graphics accelerator provides pixel processing and rendering functions. The NS MediaGX MMX-Enhanced Processor represents a new generation of x86-compatible 64-bit microprocessors with sixth-generation features. The decoupled load/store unit (within the memory management unit) allows multiple instructions in a single clock cycle. Other features include single-cycle execution, single-cycle instruction decode, 16KB write-back cache, and clock rates up to 266MHz. These features are possible by the use of advanced-process technologies and super pipelining.

2.2 DMA CONTROLLER

The equivalent of two 8237A DMA controllers are implemented on the AR-B1570 board. Each controller is a fourchannel 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-speed 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 for the DMA channels:

Slave with four 8-bit chnls Master with three 16-bit chnls

DMA Controller 1 DMA Controller 2

Channel 0: Spare Channel 4(0): Cascade for controller 1

Channel 1: IBM SDLC Channel 5(1): Spare

Channel 2: Diskette adapter Channel 6(2): Spare

Channel 3: Spare Channel 7(3): Spare

DMA Channel Controller

AR-B1570 User’s Guide

2.3 KEYBOARD CONTROLLER

The 8042 processor is programmed to support the keyboard serial interface. The keyboard controller receives serial data from the keyboard, checks its parity, translates scan codes, and presents it to the system as a byte data in its output buffer. The controller can interrupt the system when data is placed in its output buffer, or wait for the system to poll its status register to determine when data is available.

Data can be written to the keyboard by writing data to the output buffer of the keyboard controller.

Each byte of data is sent to the keyboard controller in a series with an odd parity bit automatically inserted. The keyboard controller is required to acknowledge all data transmissions. Therefore, another byte of data will not be sent to keyboard controller until acknowledgment is received for the previous byte sent. The “output buffer full” interruption may be used for both send and receive routines.

2.4 INTERRUPT CONTROLLER

The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B1570 board. They accept requests from peripherals, resolve priorities on pending interrupts in service, issue interrupt requests to the CPU, and provide vectors which are used as acceptance indices by the CPU to determine which interrupt service routine to execute. These two controllers are cascaded with the second controller representing IRQ8 to IRQ15, which is rerouted through IRQ2 on the first controller.

The following is the system information of interrupts levels:

Interrupt Level Description

NMI Parity check CTRL1 IRQ0 IRQ1

IRQ2

CTRL2

System timer interrupt from timer 8254

keyboard output buffer full Rerouting to IRQ8 to IRQ15

IRQ8:Real time clock IRQ9:Reserved IRQ10:LAN adapters(based on PCI INT routing) IRQ12:Reserved for PS/2 mouse IRQ13:Math.Co-processor IRQ14:Hard disk adapter IRQ15:Hard disk adapter

2.4.2 Real-Time Clock and Non-Volatile RAM

The AR-B1570 contains a real-time clock compartment that maintains the date and time in addition to storing configuration information about the computer system. It contains 14 bytes of clock and control registers and 114 bytes of general purpose RAM. Because of the use of CMOS technology, it consumes very little power and can be maintained for long periods of time using an internal Lithium battery. The contents of each byte in the CMOS RAM are listed as follows:

Real-Time Clock & Non-Volatile RAM

2.4.3 Timer

The AR-B1570 provides three programmable timers, each with a timing frequency of 1.19 MHz.

Timer 0 The output of this timer is tied to interrupt request 0. (IRQ 0)

Timer 1 This timer is used to trigger memory refresh cycles.

Timer 2 This timer provides the speaker tone.

Application programs can load different counts into this timer to generate various sound frequencies.

AR-B1570 User’s Guide

2.5 SERIAL PORT

The ACEs (Asynchronous Communication Elements ACE1 to ACE4) are used to convert parallel data to a serial format on the transmit side and convert serial data to parallel on the receiver side. The serial format, in order of transmission and reception, is a start bit, followed by five to eight data bits, a parity bit (if programmed) and one,

1.5 (in a five-bit format only) or two stop bits(in a 6,7, or 8-bit format). The ACEs are capable of handling divisors of 1 to 65535, and produce a 16x clock for driving the internal transmitter logic.

Provisions are also included to use this 16x clock to drive the receiver logic. Also included in the ACE a completed MODEM control capability, and a processor interrupt system that may be software tailored to the computing time required to handle the communications link.

The following table is a summary of each ACE accessible register
