Renesas RZ/G2L MPUs Feature Cortex-A55 & Cortex-M33 Cores for AI Applications

Block Diagram of RZ-G2L

Renesas Electronics Corporation announced RZ/G2L MPUs, allowing enhanced processing for an extensive variety of AI applications. The RZ/G2L group of 64-bit MPUs includes three new MPU models featuring Arm Cortex-A55, and an optional Cortex-M33 core. These are RZ/G2L, RZ/G2LC, and RZ/G2UL MPUs. The Cortex-A55 CPU core typically delivers approximately 20 percent improved processing performance compared with the previous Cortex-A53 core, and according to Renesas, is around six times faster in “essential processing for AI applications”. The company already has four mid to high-end design level MPUs including RZ/G2E, RZ/G2N, RZ/G2M, and RZ/G2H, with combinations of Cortex-A53 and Cortex-A57 cores. The new RZ/G2L group of three MPUs forms the entry-level design with Cortex-A55. Hence, the seven MPU models together provide scalability from entry-level to high-end design. Common Key Features in RZ/G2L, RZ/G2LC, and RZ/G2UL MPUs Up to 2x Cortex-A55 cores Cortex-M33 core Camera interface (MIPI-CSI) Display interface (Parallel-IF) USB2.0 interface 2ch, […]

Renesas Launches RA6M4 Cortex-M33 Microcontrollers for Secure IoT Applications

Arm Custom Instructions Coming to Armv8-M Embedded Processors

So far Arm defined all instructions for their cores with the benefit of code portability between solutions, so code compiled for an Arm Cortex-M33 based microcontroller would run on another without modifications (we’re obviously talking about code running directly on the core, not using specific peripherals here). But with RISC-V open-source architecture many have seen the benefit of custom instructions for specific tasks, at the risk of potential fragmentation. With Arm Techcon 2019 now taking place, Arm has just announced support for custom instructions for ARMv8-M embedded CPUs starting with Arm Cortex-M33 cores. The implementation of Arm Custom Instructions for specific embedded and IoT applications will start in H1 2020 at no additional cost to licensees and without risk of software fragmentation using NOCP exception if the instructions are not available. Arm futher explains: Arm Custom Instructions are enabled by modifications to the CPU that reserve encoding space for designers […]
