VPX SBC Blends FPGAs And Dual-Core PowerPC Processors

High-speed Aurora or Serial FPDP links feed dual Xilinx Virtex-5 FPGAs via a pair of FPGA mezzanine card (FMC/VITA 57) slots on VMetro’s latest VPX single-board computer (SBC). The HPE640 also includes two Freescale MPC8641D dual e600 PowerPC cores. The PowerPC chips have access to 2 Gbytes of DDR2 SDRAM. Each FPGA has access to six banks of memory (36 Mbytes of SRAM via four banks, 256 Mbytes of DDR2 SDRAM via two banks). A Gigabit Ethernet switch provides four links to the backplane and to each MPC8641D. A matching Serial RapidIO switch provides a similar communication complement. Distributed communication is supported by VMetro’s FusionIPC, which works across the range of VMetro’s boards, including the quad FPGA FPE650 and the HPE720. The HPE720 has a single processor plus a pair of FPGAs driving an FMC slot and an XMC/FMC slot.
