1 Introduction

AM62Px contains up to four Arm®-Cortex®-A53 cores with 64-bit architecture, a Cortex-R5F MCU core, a Cortex-R5F Device Management core, and various other features including: multi-high definition display support, 3D-graphics acceleration, 4K video acceleration, and extensive peripherals make the AM62Px well-suited for a broad range of automotive and industrial applications, including automotive digital instrumentation, automotive displays, industrial HMI, and more. It supports LPDDR4 32-bit width with speed of 3200 MT/s. Figure 1-1 is a functional block diagram for AM62Px. For details, see AM62Px Sitara Processors Data Sheet.

This document presents a number of industry standard and application specific benchmarks measured on the AM62Px processor. The tests focus on the performance of the Arm-Cortex-A53 cores and the LPDDR4 memory with some application specific benchmarks for the Arm-Cortex-R5F MCU, GPU , and other components. The key parameters of the evaluation board are 1.25GHz and 1.4GHz clock speed for the Arm-Cortex-A53 cores, 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 9.02.
