    99This mono-processor application read a stream of images (128 lines * 128 pixels / 1 byte per pixel), from a file on a FAT32 disk controller, and display it interactively on the frame buffer. The ''images.raw'' file available in the application directory contains 20 images. This application can be used to test peripherals such as block devices, frame buffer, and dynamic allocation of  TTY terminals.
