1 Introduction

AM62Lx is a System-on-Chip (SoC) containing dual Arm®-Cortex®-A53 cores with 64-bit architecture. AM62Lx is equipped with several embedded features such as Multimedia DSI/DPI support, integrated ADC on chip, advanced lower power management modes, and extensive security options for IP protection. The device includes several peripherals which enable system-level connectivity such as USB, MMC/SD, OSPI, CAN-FD and an ADC. Figure 1-1 is a functional block diagram for AM62Lx. For details, see AM62Lx Sitara Processors Data Sheet.

This document presents a number of industry standard and application specific benchmarks measured on the AM62Lx processor. The tests focus on the performance of the Arm®-Cortex®-A53 cores and the LPDDR4 memory with some application specific benchmarks. The key parameters of the evaluation board are 1.25GHz clock speed on the Arm®-Cortex®-A53 cores and 16-bit wide LPDDR4 with speed of 1600 MT/s. Most of the standard benchmarks are already included in the SDK and can be directly executed while the other benchmarks can be downloaded from the respective official host websites.
