MoSys MSR576

Each FPGA on the development board supports a 576-Mb MoSys MSR576 Bandwidth
Engine SRAM interface for very-high-speed sequential memory access. The 16-bit
transceiver based interface can run up to 10.3125 G per channel, which encapsulates
four SRAM memory interfaces internally, each with a 2Mx72 configuration. Each
interface supports up to 18.6 GB/s read memory bandwidth.

Table 2–27

lists the MoSys MSR576 interface pin assignments, signal names, and

functions relative to the Stratix V GX FPGAs.
