JPEG Codec Full HD(YUV422) 24fps@100MHz.(1sample/clk)

Overview

Key Features

• •The arithmetic accuracy satisfies the requirement of compliance testing of JPEG Part2 (ISO/IEC10918-2).
• • Image Data I/O Format:Block Interleaved Format.
• • Image Size:Any size that can be divided by MCU unit.
• • Operation mode like processing mode, image size, DRI value etc. are set in internal register via external CPU.
• • Quantization table / Huffman table:Written from external during compression, and downloaded from compressed data during decompression.
• • Marker:Automatically generated during compression, and automatically deciphered during decompression. Processed marker: SOI,SOF0,SOS,DQT,DHT,DRI,RSTm,EOI
