4. Description of Selection Criteria Software Complexity: –Complexity of VHDL development based on projected time for coding. (i.e. utilizing basic Bluetooth modules provided would require extensive coding of Bluetooth stack, thus adding a significant amount of time to the VHDL development) Bluetooth Complexity: –Two different approaches to Bluetooth have been provided (Bluetooth modules and Parani development board). Utilizing the modules will require custom logic/coding as well as a large amount of hardware development. Hence, more complex with Bluetooth modules over Parani (which is simply RS232) Cost: –Lower cost beneficial Size: –Smaller size beneficial. This stems from possible application in robotics platforms where this system would be mounted on a robot. Thus, smaller is better. Memory Speed: –Want fast speed of memory so that don’t run into bottlenecks of P08311 (for their project, the Compact Flash memory that they used was much too slow for the application). DAQ-FPGA Interface Complexity: –Simpler the interface, less chance of data being lost or data transmission to be slowed down. Processor: –Embedded processor posed problems in complexity of coding/communication for P08311. Moving away from embedded processor will be desired.
