The World's First Dual-Core Real-Time Control MCU Featuring Processor Unveiled at Electronica China 2024
Next-Generation Advanced Core and Enhanced DSP and AI Real-Time Master Control Chip
The Arm® Cortex®-M52 processor, built on the Arm® v8.1-M architecture, elevates the efficiency of the Cortex-M series (including Cortex®-M55 and Cortex®-M85) to a new level and marks a significant milestone in integrating machine learning (ML) functionality into microcontrollers.
With Arm Helium™ technology and the M-Profile Vector Extension (MVE) based on the Arm v8.1-M architecture, the Cortex-M52 achieves superior DSP and ML functionalities. Compared to previous generations of the Cortex-M series, the Cortex-M52's ML performance is up to 5.6 times higher, and its DSP performance is up to 2.7 times greater. Additionally, the Cortex-M52 supports a custom data path extension (CDE) interface, which enables integration with Geehy's high-performance, low-latency ZiDian™ math computation acceleration unit. This unit significantly reduces mathematical computing time and CPU access latency by supporting multiple mathematical computing accelerations at the instruction set level. Therefore, the Cortex-M52 meets the stringent requirements of new-generation high-efficiency digital power and industrial control applications for real-time performance and AI.
Based on a 40nm advanced process, the real-time control MCU series features an embedded Cortex-M52 core, a ZiDian™ math computation acceleration unit, and high-performance control peripherals. It operates in environments ranging from -40℃ to 125℃. With its innovative architecture, the G32R5 dramatically improves real-time computing power. When the dual-core runs at a 250MHz main frequency, its real-time computing power is comparable to that of Cortex-M7 core products with an 800MHz frequency, meeting the needs of next-generation server power supplies, DC charging station power modules, photovoltaic inverters, on-board chargers, and high-performance motion control, and other applications.
