Fixed Length Visually Lossless Compression [RGB/YCbCr]
Overview
TMC’s original compression algorithm enables to compress and decompress the images to fixed-length with completely independent small block units. By using this technology, the memory capacity, data transmission bandwidth, and power consumption required for image data processing can be significantly reduced.
Optimized design according to the application have achieved a compact circuit size and ultra-low power consumption performance. In addition, by using a small rectangular pixel set (block) as the processing unit, it has the following features.
