1.1 Microprocessor
The MBM-530NS uses the NS GX1-300 CPU (or other GX1 CPUs); it is an
advanced 64-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 Cx5530A 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 CX5530A
provides an Ultra DMA/33 interface, MPEG2 assist, and is AC97 Version 2.0
audio compliant.
