Swan

™ ES4118

Super VCD Processor

Product Brief

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

and ADCs.

Figure 1 shows a block diagram of a typical

standalone system, using the ES4118 with the glueless SDRAM

interface.

The SVCD data system stream from a CD disc is passed to the

layer and demultiplexes the audio and video streams. Audio is

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.
