ES7020 Vantage-II Audio/Video Codec Product Brief DESCRIPTION The ES7020 Vantage™-II codec is a highly integrated superior performance chip that combines an advanced MPEG-2 decoder with a sophisticated MPEG-2 encoder and an NTSC/PAL encoder. The ES7020 provides time b a se co rre ct i o n ( T BC) f o r r e c o r d i n g f r o m VCR videocassette tapes with weak signals without loss of synchronization, low delay monitoring of decoded video output signal, ATAPI interface, built-in CPRM encode/ decode, state-of-the-art progressive-scan video, and S/ PDIF input and output support. The MPEG encoder portion does flexible NTSC or PAL encoding on a YUV 4:2:2 stream in response to firmware control of the internal CPU. The internal CPU, in conjunction with an additional hardware accelerator, allows for very flexible encoding and allows for additional functionality to be easily added. An audio DSP engine facilitates the encoding of MPEG-1 layer 2 audio while the host CPU interface unit allows for easy reading of close caption data. In addition, the ES7020 has inverse 3:2 pull- down capability, allowing it to dynamically analyze incoming fields and compress from 60 fields to 24 frames in the case of film material. The MPEG decoder portion is built on the ESS proprietary dual CPU Programmable Multimedia Processor (PMP), consisting of a 32-bit RISC processor and a 64-bit vector engine. This architecture is extremely programmable and allows for the best DVD feature set. The RISC processor performs bit stream parsing, transfers data to the vector engine, and manages the chip as a whole. The vector engine performs all the computationally intensive tasks required by applications such as Dolby® Digital, DTS Surround™, and MPEG and JPEG imaging. These tasks include video motion compensation and estimation, loop filtering, discrete and inverse discrete cosine transforms (DCT/IDCT), quantization, and inverse quantization. The ES7020 with DTS support is offered with the ES7020D, which has the same pinout as the standard ES7020. The ES7020 and ES7020D are available in an industry-standard 388-pin BGA package.
