4. Major Design Constraints Number of I/O pins on the microcontroller Memory space on micro for embedded C libraries and character look-up tables Total cost should be less than similar products (Maximus ~ $2000) Availability of IP for VGA controller

5. Micro Selection Chose Microchip PIC32MX360F512L –Plenty of general purpose IO pins (85) –Plenty of flash (512kB) –Familiar with MIPS architecture –Low cost; few un-needed periphreals Alternatives –PIC32MX360F256L (256kB flash, 85 IO pins) –PIC32MX320F032H (32kB flash, 53 IO pins)

6. FPGA Selection Chose Altera Cyclone II –Used extensively in ECE437 –Reference design available for VGA controller –Low cost and power Alternatives –Altera Stratix II –Actel ProASIC3 –Xilinx Spartan-3
