Crypto Benchmark on Synergy S7 MCU
ARM Cortex-M4 @ 240 MHz
This benchmark conducted on SK-S7G2 Starter Kit (RTK7SKS7G2S00003BU) will help you in qualifying performance of CycloneCRYPTO (Cryptography library), CycloneSSL (TLS 1.3 & DTLS 1.2 library), CycloneSSH (SSH library with SCP & SFTP protocols), CycloneIPSEC (IPsec/IKEv2 library) and CycloneTCP (TCP/IPv4/IPv6 stack with secure protocols like HTTPS, FTPS, MQTTS, Secure WebSocket, Secure CoAP, Secure Modbus/TCP, SNMPv3...) running on Renesas Synergy S7 microcontroller.
Synergy S7 MCU also includes crypto hardware acceleration. In the following comparison charts, both hardware and software performance are presented in the relevant sections.
