2. המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory Abstract Many programs require several DSPs in order to process their data as quickly and efficient as possible. In this project we designed some sort of a communication center for several DSPs and one PC, which connects all of them, so that data is transferred easily between them. The communication protocol we used is the McBSP protocol. 2

3. המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory Project Requirements Hardware Implementations: 1.Designing and implementing a switch matrix, which is able to transfer Data between all 8 McBSP ports and the HOST PC. 2.Implementing a communication unit with the McBSP interface, which transfers data to and from the DSPs. 3. Implementation of the interface between the switch matrix and the HOST PC.      The whole project was implemented in VHDL on the ALTERA FLEX 10KE Development Kit’s FPGA. Software Implementations: 1.   Writing a driver (using WINDRIVER), which enables communication to the HOST PC. 2.   Writing a program sends and receives data from the HOST PC to each DSP and from each DSP to the HOST PC. 3.   Writing a program that configures the connections between the ports in the Switch Matrix. 4.    Writing a program to transfer data to/from the DSP on the DSP’s flash memory using the TI Code Composer. 3
