Parallel compressing system for satellite on programmable chip Yifat Manzor Yifat Manzor & Reshef Dahan Supervisor: Eran Segev Part B

Satellite image Input Data rate from one sensor line   B/W Picture   Range – 2.5 km width   Velocity - 8 km/sec   4 Pixels per 1m ² Rate = 80 Mpix/sec Streaming Data 12-bit per pixel 5,000 pix 16,000 lines/sec 80 Mpixel image

System demands: » 80Mpix/sec input data rate. » Image width – 5000 pixel ADV202 Single compressing chip capabilities: » 27 Mpix/sec maximum input data rate » 25 MByte/sec maximum output rate » Maximum image width – 4096 pixel » Maximum image length – infinity

Solution MAIN IDEA To generate parallel processing by separating the picture to 3 compressors 1667pix 1666pix 3 16,000 lines/sec Tile
