SiFive Licenses Flex Logix eFPGA for Lower Power Communications SoC

MOUNTAIN VIEW, Calif., Dec. 7, 2020 - Flex Logix® Technologies, Inc., supplier of the fastest and most-efficient AI edge inference accelerator and the leading supplier of eFPGA IP, announced today that OpenFive, a leading provider of domain-specific custom silicon solutions with differentiated IP, has licensed the EFLXÒ eFPGA for use in a low power communications SoC, powerful and flexible enough to be used in data center and edge applications, for a mutual customer of OpenFive and Flex Logix.

eFPGA for Communications Applications
Communications systems today are major users of FPGAs for flexibility and reconfigurability for customization and real-time updating of protocols and algorithms. Flex Logix's EFLX eFPGA allows systems to be smaller, lighter and lower power by integrating the FPGA into the application-specific integrated circuit/system-on-a-chip (ASIC/SoC) compared to the traditional method of using an external FPGA.

"We are proud to work with OpenFive and our joint customer who extensively evaluated Flex Logix's technology," said Geoff Tate, CEO of Flex Logix. "Because our eFPGA can deliver significant improvements in performance, power and reconfigurability, we are seeing more opportunities to work with a premier custom silicon solution provider such as OpenFive. Customers can benefit greatly from having RTL configurability in their ASICs."

"We're honored to have Flex Logix as an eFPGA partner, not only because their EFLX eFPGA offers density, performance and the ability to do large arrays, but also because the company has achieved many customer tape-outs in various applications including aerospace, communications ASICs and low power MCUs," said Shafy Eltoukhy, CEO of OpenFive. "Flex Logix's eFPGA offerings are also easy to integrate across most process nodes, enabling OpenFive to deliver domain-specific custom silicon solutions with differentiated IP that are optimized for power, performance and area."

The EFLX4K Logic IP core has 4K 4-input-equivalent-LUTs, 632 inputs and 632 outputs and is a complete eFPGA. The EFLX4K DSP IP core replaces about one-fourth of the LUTs with 40 multiplier-accumulators for DSP and artificial intelligence (AI) applications. The two EFLX4K cores can be tiled together to make larger arrays to support applications needing more LUTs as required, up to 7x7 with any mix of logic and DSP cores.

The EFLX arrays are programmed using VHDL or Verilog. The EFLX Compiler takes the output of a synthesis tool such as Synopsys SynplifyÒ and does packing, placement, routing, timing and bitstream generation. The bitstream, when loaded into the array, programs it to execute the desired RTL.
