Fujitsu's video processing IC with embedded memory

Fujitsu Ltd rolled out an LSI chip that can compress and decompress full HD video (1,920 dots x 1,080 lines) in the H.264 format in real-time. The MB86H51 chip is said to be the industry's first one-chip LSI for full HD H.264 high profile video processing with embedded memory.

This new chip enables high image quality recording, playback and transmission of full HD video over a wide range of fields from consumer to industrial applications, such as for digital video cameras (camcorders), hard disk digital video recorders (DVRs), home network devices, security cameras and broadcasting equipment.

MB86H51 is an enhanced version of Fujitsu's MB86H50 chip for HD (1,440 X 1,080) that is currently shipping. The new chip uses high-compression technology from Fujitsu Laboratories Ltd to reduce processing burden, while leveraging embedded memory technologies from Fujitsu Ltd to enable compactness and low power consumption.

Product features
The LSI chip contains two blocks of 256Mbit memory (FCRAM) embedded on-chip, and uses optimized LSI design to realize smaller size and low power consumption.

Compared to previous formats, real-time H.264 format video compression requires more than 10 times the data processing that was necessary for previous formats. By realizing further high-speed processing, Fujitsu's new chip can support H.264 High Profile Level 4.0. With the new chip audio is compressed and decompressed in real-time by using formats such as MPEG-1 Audio Layer.

This chip utilizes a proprietary algorithm developed by Fujitsu Laboratories that automatically applies less compression to areas in the image where compression artifacts are most noticeable, such as human faces or slow-moving objects, and greater compression to other areas. Thus, high image quality for the critical zones is maximized. This feature also makes it possible for image size to be reduced to one-half to one-third that of the MPEG-2 format with an equivalent level of image quality.

Sampling of the device will begin July 1. Sample price starts at $247.
