? 基于RZ/G2L核心板设计的HDG2L-IoT开发板，两路千兆网口实测基本达到1000Mbps的最大速率。
• The HDG2L-IOT development board, based on the RZ/G2L core board design, provides a two-way gigabyte portal with a near maximum speed of 1,000 Mbps.
? 注：千兆以太网接口分别采用Microchip与裕太PHY芯片进行了测试，速率相近。?
Note: Microchip and Xuta PHY chips have been tested separately at a rate similar to that of the Giga Ether interface.
? 评估测试RZ/G2L核心板环境适应性，测试低温启动、高温工作、高低温循环状态下的工作情况。
• Assess the environmental adaptation of the RZ/G2L core plate and test the performance of low-temperature start-up, high-temperature work, high-temperature cycling.

? 瑞萨高端MPU平台RZ/G2L有很多可圈可点的地方，例如搭载了双核A55+Cotex-M33处理器，集成高性能Mail-G31?GPU等的核心板，万象奥科评测套件也提供了完善健壮的外设驱动设备支持，还有在不同温度环境下的稳定性能，都给这款开发板加分不少。
The RZ/G2L, a high-end MPU platform in Risa, has a number of niches, such as a dual-nucleic A55+Cotex-M33 processor, the integration of core boards such as high-performance Mail-G31?GPU, which is supported by a robust outer power drive by the Vientiane Oko assessment package, and stability in different temperature environments, all of which add a lot to the development panel.
