Hex Five adds MultiZone Security to the Andes RISC-V Cores on GOWIN FPGAs

The first RISC-V Trusted Execution Environment Enabling Robust Security for Andes N(X)25 RISC-V Cores on the GOWIN GW-2A Family of FPGAs

SAN JOSE, CA – Nov 9, 2018 /PRNewswire/ – Hex Five Security, Inc, the creator of MultiZone™ Security, Andes Technology Corporation and GOWIN Semiconductor Corp announce a collaboration to enable MultiZoneTM Security, the first Trusted Execution Environment for RISC-V on the Andes N(X)25 RISC-V Cores, which is part of 25-series, with the GOWIN GW-2A Family of FPGAs.

Hex Five’s patent pending technology provides policy-based hardware-enforced separation for an unlimited number of security zones, with full control over data, code, interrupts and peripherals. MultiZone’s™ Configurator takes fully compiled and linked customer code and merges it with Hex Five’s nanoKernel to enable rapid adoption without any changes to hardware or customer code basis.

Andes 32-bit N25(F)/A25, and 64-bit NX25(F)/AX25 are versatile CPU cores compliant to RISC-V ISA that deliver over 3.5 CoreMark/MHz and 1.3 WMIPS/MHz for single precision floating point. Their common features include dynamic branch prediction, instruction and data caches, local memories, and Andes Custom Extension™ (ACE) to simplify instructions design for Domain-Specific Acceleration. All cores support User/Machine mode, while the A25/AX25 add Supervisor mode and MMU for Linux kernel and its applications.

“The Chinese market will be the first mass adopter of RISC-V,” said Dr. Charlie Su, CTO and Senior VP of Andes.  “We’re happy to work with Hex Five to provide our customers a simple, robust security implementation that based on our RISC-V cores and comprehensive AndeSight™, an eclipse-based development environment and optimized toolchains to provide leading performance and reduced development time.“

“Increasingly customers in China see security as core requirement of their products,” said Jim Gao, Director of Solution Development, GOWIN Semiconductor.  “With MultiZone Security, they can implement a robust security solution on our existing FPGAs without the need for new hardware, deep security expertise or even any changes to their toolset and workflow.  This allows a customer to get to market fast, which is the whole point of our FPGAs.”

“The cost of a robust security implementation on RISC-V is now negligible – the future of RISC-V is security by default.” said Don Barnetson, co-founder of Hex Five Security.  “We’re very excited to enter the Chinese market with such strong partners and expand access to simple, robust security that any developer can  implement.”

Hex Five, Andes and GOWIN Semiconductor will demonstrate MultiZone™ Security at Andes RISC-V CON on Nov 13, 2018 at Andes RISC-V CON in Santa Clara, CA.
