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
base correction (TBC) for recording from 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.
