Notes:
- FPGA and CPU share 8 MBytes of RAM via DSP EMIF, 100 MHz clock rate maximum.
- The V5 uses 6 input lookup table (LUT) functions vs. 4 input LUTs on Spartans.
- Soft FPGA MAC cores are available for 10/100 Mbit Ethernet Phy Control.
- 1000 Mhz CPU configurations are available for MityDSP-Pro cards.
- TMS6455 Option Including 8 Rocket I/O ports is available upon request.
