### AI overview

Renesas introduced the RZ/G3L and RZ/G3SE, two 64-bit MPUs for HMI and IoT edge systems. Both use Arm Cortex-A55 application cores and an Arm Cortex-M33 real-time coprocessor. The RZ/G3L adds a Mali-G31 GPU and H.264 codec for richer HMI applications, while the RZ/G3SE targets IoT devices with basic display needs. Both support low-power standby operation.

### Source excerpt

Renesas has expanded its RZ/G Series with the RZ/G3L and RZ/G3SE, two new 64-bit MPUs for HMI and IoT edge systems. Both devices integrate up to four Arm Cortex-A55 application cores clocked at up to 1.2 GHz and a 200 MHz Arm Cortex-M33 real-time coprocessor. The two chips are pin-to-pin compatible but target different applications. The RZ/G3L integrates an Arm Mali-G31 3D GPU and H.264 video codec for HMI applications like retail terminals and medical devices. The RZ/G3SE removes the GPU and video codec and is designed for IoT devices with basic display requirements, including EV chargers and industrial gateway devices. Both can reduce standby power consumption to around 1 mW and resume operation quickly from deep standby, which is useful for devices that need to remain connected while consuming very little power.

### AI overview

This article introduces tracing and profiling for embedded systems using Zephyr RTOS. It explains how tracing records execution data from functions, threads, and interrupts, while profiling measures metrics such as execution time, CPU usage, and dynamic memory usage. It also demonstrates Zephyr's native tracing workflow on an ESP32-C6 and introduces Percepio's Tracealyzer as a third-party analysis tool.

### Source excerpt

This is an introduction to the critical embedded system debugging techniques of tracing and profiling within the Zephyr RTOS. After reading this article, you can use Zephyr's native tracing tools to gain a visual, in-depth understanding of system dynamics, helping to evaluate performance, spot timing issues, and diagnose complex problems like memory leaks or thread interaction glitches.
