Main Chipset

The AML3400 HD A/V processor is a completely integrated system targeting all types of high definition Audio/Video processing applications. The AML3400 combines full function MPEG-2 and HVD decoding, numerous dedicated and general-purpose peripherals, and an embedded 32-bit host CPU in a single device. The AML34QG has two high speed AMRISC™ 24-bit RISC processors with special instructions to accommodate audio and HD video digital signal processing.

The embedded 32-bit host CPU handles system initialization, DVD navigation and other system applications. The AML3400 A/V processor provides a glueless interface to all external components ATAPI loaders, Thomson serial front-end devices, audio DACs and memory. Numerous general-purpose I/O pins can be used to control the front panel display and other miscellaneous tasks. The Flash interface allows the Flash memory to be shared with the front-end chip to reduce system cost in mono-board designs. Together, the embedded host CPU and special glueless interfaces reduce the total system cost for high definition A/V applications.

The AML34QO HD A/V processor is equipped with an NTSC/PAL TV encoder, picture-in-picture (PIP), and picture in graphics (PIG) capability. It supports S-Video, composite, YUV component and RGB. The video encoder also supports high-quality de-interlaced progressive scan (48Qp/576p) with full Macrovision support. Contrast enhancement, hue adjustment, video scaling, video interpolation, pan-scan, letter-box, and zoom are also supported. The AML3400 supports High Definition Output (720p/1080i/1080p) and supports simultaneous output of progressive (480p) and interlaced (48Qi) video. In addition, built in Video DACs complement the video encoder further reducing system cost.

The integrated AMRISC™ RISC processor is designed to support advanced digital audio processing. The micro-coded engine provides support for all existing audio formats and it also has enough flexibility and headroom to accommodate future audio standards. Popular audio formats like Dolby AC-3 5,1, DTS, HDCO, MP-3 and WMA are supported. The AML34QO also has an IEC958 digital input to accommodate DVD A/V Receiver applications.
