QDRII+ Top Port 0
The QDRII+ top port 0 consists of a single QDRII+ burst-of-4 SRAM, providing
4 Mbyte with an 18-bit read data bus and an 18-bit write data bus.
This memory interface is designed to run between 120 MHz, the minimum frequency
for this device, and 400 MHz for a maximum theoretical bandwidth of over 14.4 Gbps
for reading and 14.4 Gbps for writing. The internal bus in the FPGA is typically 2 or 4
times the width at full rate or half rate respectively. For example, a 400 MHz 18-bit
interface becomes a 200 MHz 72 bit bus.
