SiFive Partners With Coherent Logix for Mission-Critical Processor Solutions

SiFive Core IP Enables Market-Leading Applications for Military and Aerospace Markets

SAN MATEO, Calif.–(BUSINESS WIRE)–SiFive, Inc., the leading provider of commercial RISC-V processor IP and silicon solutions, today announced that Coherent Logix has chosen SiFive Core IP to complement its HyperX™ memory network processor for its next-generation solutions targeting mission-critical markets. Coherent Logix performed a comparison of CPU IP available in the market based on requirements of the military and aerospace customers and selected SiFive IP that enabled very low Size, Weight, Area, and Power (SWAP) of the overall solution.

“SiFive Core IP enabled us to quickly design a HyperX™ architecture-based customized solution which met the target platform requirements,” said Michael Doerr, CEO of Coherent Logix. “SiFive’s flexible business model enabled a seamless engagement for us while offering market-leading SWAP for our end customer.”

The Coherent Logix HyperX™ Platform provides the tools and libraries needed to solve mission-critical problems in multiple disciplines, including hyperspectral and multispectral image/data fusion, software-defined radio, synthetic aperture radar, portable sensor systems, remote sensor platforms, surveillance receivers, anti-jam Global Positioning System, automatic target recognition and threat cueing, ad-hoc networking, and secure data transmission. The Coherent Logix HyperX™ platform features a large library of supported waveforms and delivers these capabilities in a low-power, high-performance environment.

SiFive’s Custom Instruction Extension feature accelerates domain-specific workloads, a key requirement for military and aerospace customers. SiFive has an extensive IP portfolio that can be used for solutions with SWAP constraints. In comparison to other solutions in the market, SiFive provides high-performance solutions with half to third of the power of competitor solutions1. SiFive Core IP deterministic real-time processing capabilities support low latency mission-critical workloads.

“We are pleased to partner with Coherent Logix on their next-generation design for mission-critical markets,” said Dr. Naveed Sherwani, CEO of SiFive. “The SiFive Core IP portfolio complements CLX HyperX processor technology perfectly to create a scalable, low power, high-performance solution for mission-critical applications.”
