Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 This project is the basis for further projects with purpose to connect video cameras to users on PC’s. The challenge of project is to send video stream via McBSP channels and not by USB. Project consist of programs to TI’s DSP platform- TMS320C6701 Evaluation Module,and for PC. Evaluation module receives data from another TI platform IDK with video camera.IDK receives and processes data stream and sends it to EVM on two McBSP channels.EVM only transfers it to PCI bus using buffers to avoid conflicts between writes and reads of data. PC program uses help function (given by TI with driver for EVM) to transfer data from EVM to PC and stores it in file.Speed of internal logics of EVM and McBSP is sufficient for needs of system and do not disturb PCI bus operation.
