12.1 OVERVIEW OF JPEG CODEC
JPEG codec compresses the original raw image and decompress the JPEG encoded image. It performs all
functions required for image compression/ decompression such as Discrete Cosine Transform (DCT),
Quantization and Huffman coding. It comprises of control circuit, DCT/Quantization, Huffman codec, marker
process block and AHB interface control as shown in
conditions such as the Huffman table number and restart interval value into internal control registers.
