R Design Trade-Offs 8-pin DIP socket for auxiliary clock oscillator Design Trade-Offs A few system-level design trade-offs were required in order to provide the MicroBlaze Development Kit board with the most functionality. Configuration Methods Galore! A typical FPGA application uses a single non-volatile memory to store configuration images. To demonstrate new Spartan-3E capabilities, the MicroBlaze Development Kit board has three different configuration memory sources that all need to func
