v4 v5 9 9 This 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. 10 10 11 It requires one private TTY terminal. 12 11 13 The source code can be found [source:soft/giet_vm/applications/display/main.c here]. 12 14 … … 17 19 The input and output buffers containing the image are distributed in all clusters. 18 20 19 The number of clusters must be a power of 2 no larger than 32 20 The number of processors per cluster must be a power of 2 no larger than 4 21 The number of clusters must be a power of 2 no larger than 32. 22 The number of processors per cluster must be a power of 2 no larger than 4. 23 24 It requires one private TTY terminal. 21 25 22 26 For each image the application makes a self test (checksum for each line). The actual display on the frame buffer depends on frame buffer availability. … … 25 29 26 30 == __Convol__ == 31 32 The source code can be found [source:soft/giet_vm/applications/convol/main.c here]. 27 33 28 34 == __Classif__ == … … 57 63 58 64 Instrumentation results display is done by the "store" task in cluster[0][0] when all "store" tasks completed the number of clusters specified by the CONTAINERS_MAX parameter. 65 66 The source code can be found [source:soft/giet_vm/applications/classif/main.c here].
