ES4118F

The Swan^TM 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(TM) technology that is useful for video standards conversion. SmartStream(TM) 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 I² S interface supports popular audio DACs and ADCs.  Figure 1 shows a block diagram of a typicalstandalone 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 I² S interface. The ES4118 parses the system layer and demultiplexes the audio and video streams. Audio is decoded and passed through the I² S audio serial bus to an 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.
