1 Introduction

AM62Ax contains up to four Arm®-Cortex®-A53 cores with 64-bit architecture, a Cortex-R5F MCU core, a Cortex-R5F Device Management core, a single core C7x256v DSP with MMA, and various other accelerators such as Video and Vision processing, display interface with extensive peripheral and networking options. It supports LPDDR4 32-bit width with speed of 3200 MT/s. #FIG_YMH_MB4_QWB is a functional block diagram for AM62Ax. For details, see AM62Ax Sitara Processors Data Sheet.

This document presents a number of industry standard and application specific benchmarks measured on the AM62Ax processor. The tests focus on the performance of the Arm-Cortex-A53 cors and the LPDDR4 memory with some application specific benchmarks for the Arm-Cortex-R5F MCU, C7x DSP core, and other memory components. The key parameters of the evaluation board are 1.25 GHz and 1.4 GHz clock speed for the Arm-Cortex-A53 cores, 1.0 GHz clock speed for the C7x DSP, and a 32-bit wide LPDDR4 at a speed of 3200MT/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 their respective official host websites. All of the benchmarks are implemented using Linux SDK 8.06.
