Create Embedded System using BSB PPC PLB Bus PLB2OPB PLB BRAM Cntlr OPB Bus PLB BRAM Cntlr PLB BRAM INTC GPIO Timer UART MY IP LEDs ICON IBA GPIO Push Buttons DIP Switches Verify HW Operation with generated Test Application

Add GPIO Cores PPC PLB Bus PLB2OPB PLB BRAM Cntlr OPB Bus PLB BRAM Cntlr PLB BRAM INTC GPIO Timer UART MY IP LEDs ICON IBA GPIO Push Buttons DIP Switches Add SW code to read state of DIP switches and Push Buttons and display on hyperterm

Summary BSB can be used to create a simple processor system targeting a specific hardware board –Generates an MHS text file that describes the embedded system hardware –Generates a Test Application to test memory and peripherals Platform generator converts the MHS to a system netlist The ISE tools generate a bitstream from the system netlist The bitstream was initialized with the software test application in EDK The bitstream was downloaded to the XUP board Output was displayed on hyperterminal
