JPEG software solution for a 32-bit MCU
Tadashi Sakamoto, Tomohiro Hase · IEEE Transactions on Consumer Electronics · 1997
New software solution for DCT-based JPEG image compression is proposed. The solution make effective use of RISC architecture and quantized DCT data domain representation. As a result, 640/spl times/480 (VGA size) YCbCr images in the 4:2:2 format can be encoded and decoded in about 0.5 of a second by using a 32-bit MCU and DRAM.
