This latest generation of the MediaGX processor enables a new class of premium performance 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 This processor is the latest member of the Cyrix 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 Cx5520 and the Cx5530 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 Cx5530 provides an Ultra DMA/33 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 with sixth-generation features. The decoupled load/store unit (within the memory management unit) allows multiple write-back cache, and clock rates up to 266MHz. These features are possible by the use of advanced-process 2.2 DMA CONTROLLER The equivalent of two 8237A DMA controllers are implemented on the AR-B9625 board. Each controller is a four- channel DMA device that will generate the memory addresses and control signals necessary to transfer information and three channels for transfers to 16-bit peripherals (DMA2).

The following topics are covered: SYSTEM CONTROLLER s GuideAR-B9625 User ¡¦ 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 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 “” 2.4 INTERRUPT CONTROLLER The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B9625 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.
