DESCRIPTION
The Swan ES4118 processor is a single-chip solution for Super
Video Compact Disk (SVCD) players that integrates MPEG
audio and video decoding, as well as system control software.
The fully programmable The ES4118 offers the best feature set
compared to existing SVCD chips and includes a glueless
interface to various peripheral components. The ES4118 is the
most cost-effective solution in its class, with levels of integration
and quality that establish new benchmarks.
The ES4118 processor is capable of decoding MPEG-2 audio
simultaneously with MPEG-1 or MPEG-2 video. For embedded
applications, the RISC processor core of the ES4118 can be
used in place of a microcontroller to provide a rich set of system
control features. On-chip, multitap filters provide arbitrary scaling
with state-of-the-art SmartScale™ technology that is useful for
video standards conversion. SmartStream™ provides video
error concealment and video postprocessing, ensuring the
highest playability and video quality.
The ES4118 connects directly with both 8- and 16-bit ROM and
with either 16-bit SDRAM ICs or with EDO DRAM ICs. An 8-bit
YUV video interface supports many TV encoders. General-
purpose auxiliary pins are provided to control various peripheral
devices. A standard I

standalone system, using the ES4118 with the glueless SDRAM
interface.
The SVCD data system stream from a CD disc is passed to the
ES4118 through the I
layer and demultiplexes the audio and video streams. Audio is
decoded and passed through the I
external audio DAC and then to the speakers. Video is decoded
and output as YUV pixels to an NTSC or PAL video encoder.
Onchip system control and housekeeping functions (keypad and
remote control) are also provided.
