Crypto Benchmark on SAMA5D3 MCU
ARM Cortex-A5 @ 528 MHz

This benchmark conducted on SAMA5D3 Xplained Evaluation Kit (ATSAMA5D3-XPLD) 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 Microchip SAMA5D3 microcontroller.

SAMA5D3 MCU also includes crypto hardware acceleration. In the following comparison charts, both hardware and software performance are presented in the relevant sections.
