Crypto Benchmark on SAM4L MCU
ARM Cortex-M4 @ 48 MHz

This benchmark conducted on SAM4L8 Xplained Pro Evaluation Kit (ATSAM4L8-XPRO) 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 SAM4L microcontroller.

SAM4L MCU also includes crypto hardware acceleration. In the following comparison charts, both hardware and software performance are presented in the relevant sections.
