Minsk, Belarus-based Promwad Innovation Company says it used uClinux to create a digital video recorder (DVR) prototype. Based on an Analog Devices Inc. (ADI) Blackfin BF533 DSP (digital signal processor), the "JPEG2000 DVR" prototype encodes images in the Motion JPEG2000 format.
Promwad's JPEG2000 DVR is designed to encode a PAL or NTSC video signal in the MJPEG2000 format, and store it to a USB flash drive, while simultaneously transmitting audio/video data to an external display. The DVR is based on ADI's BF533. Like other Blackfin DSPs, it uses the Micro Signal Architecture (MSA), which is said to support a RISC-like register and instruction model. The BF533 is equipped with two 16-bit MACs, two 40-bit ALUs, four 8-bit video ALUs, and a 40-bit shifter. Read more
