Description
The
IME6400
is a single chip MPEG4/2/1 encoder for audio, video, system. The
IME6400
encodes
audio/video, multiplex audio and video, and creates MPEG4/2/1 elementary, program and transport streams.
The
IME6400
is composed of high performance RISC processor core and DSP core with dedicated
functional blocks for real-time audio/video applications.
The
IME6400
chip performs motion estimation on a wide search area of +/-64H, +/-32V for P pictures and
+/-32H, +/-32V for B pictures at half PEL accuracy. The
IME6400
supports various motion estimation
modes such as frame, field, 16x8 mode for improving compression efficiency.
The
IME6400
operation is based on downloadable microcode, thus providing high level of flexibility and
ability to create customized solutions per specific applications, such as multi-channel systems. During
software initialization, codes are loaded into the internal program memory in one of two ways; either the
code is stored in a ROM attached on the external bus, or the code is downloaded from external host.
Program memory is extendible by optional external SRAM. To fit into low cost system implementation,
IME6400
has internal booting ROM. As the result, the overall video system can be implemented using
only one SDRAM and video decoder.
The
IME6400
requires external SDRAM for storing video frames, compressed data buffers, and user
buffers. The
IME6400
supports many SDRAM configurations to meet specific application needs. One 32
bits SDRAM, Two 16 bits SDRAM, four 8 bits SDRAM, eight 4 bits SDRAM configurations are also
possible on a 32 bits SDRAM bus. The
IME6400
generates all signals required for a glueless interface to
SDRAM memory.
The
IME6400
video interface is designed to connect directly to digital composite decoders. The industry
popular video encoders; Philips SAA7112/SAA7114, Brooktree Bt829A, Samsung KS0127 are supported.
It also can directly interface with CMOS image sensor processors for low cost application.
To minimize power consumption, the
IME6400
uses multi-clock distribution and clock-gating schemes.
The
IME6400
has two internal PLLs which provide 54Mhz clocks for core logic, and 81Mhz clocks
SDRAM interface logic. The PLL multiplies external 27Mhz clock up to 54Mhz, 81Mhz each.
The
IME6400
may be programmed to achieve useful video functions, such as scene change detection, 3 to
2 pull down, variable/constant bit rate control, etc. These powerful features enable
IME6400
to be used to
the following applications : desktop application, digital video recorders, digital camcorders, recordable
DVD, PVR, etc.
The host interface in
IME6400
is used to send compressed image data for external host. The interface
provides the functionality for applications both in the PC-based platforms or stand-alone systems.
