　　Altera’s Cyclone® V FPGAs provide the industry’s lowest system cost and power, along with performance levels that make the device family ideal for differentiating your high-volume applications. You’ll get up to 40 percent lower total power compared with the previous generation, efficient logic integration capabilities, integrated transceiver variants, and SoC FPGA variants with an ARM®-based hard processor system (HPS).

　　The Cyclone® V devices are designed to simultaneously accommodate the shrinking power consumption, cost, and time-to-market requirements; and the increasing bandwidth requirements for high-volume and cost-sensitive applications.

　　Enhanced with integrated transceivers and hard memory controllers, the Cyclone® V devices are suitable for applications in the industrial, wireless and wireline, military, and automotive markets.

　　Built on the 28-nm low power (LP) process technology, Altera’s Cyclone V FPGAs deliver the lowest power solution for applications requiring up to 5G transceivers. Compared to previous generations, Cyclone V FPGAs offer a 40-percent power reduction, with a balance of power reduction from all areas.

　　High-Bandwidth HPS-to-FPGA Interconnect Backbone

　　Although the HPS and the FPGA can operate independently, they are tightly coupled via a high-bandwidth system interconnect built from high-performance ARM AMBA® AXITM bus bridges. IP bus masters in the FPGA fabric have access to HPS bus slaves via the FPGA-to-HPS interconnect. Similarly, HPS bus masters have access to bus slaves in the FPGA fabric via the HPS-to-FPGA bridge. Both bridges are AMBA AXI-3 compliant and support simultaneous read and write transactions. Up to six FPGA masters can share the HPS SDRAM controller with the processor. Additionally, the processor can be used to configure the FPGA fabric under program control via a dedicated 32 bit configuration port.

　　HPS-to-FPGA: configurable 32, 64, or 128 bit AMBA AXI interface

　　FPGA-to-HPS: configurable 32, 64, or 128 bit AMBA AXI interface

　　FPGA-to-HPS SDRAM controller: up to 6 masters (command ports), 4x 64 bit read data ports and 4x 64 bit write data ports

　　32 bit FPGA configuration manager
