Overview of RZ/A2M
The RZ/A2M MPU is a product based on the concept of "a new-generation MPU that is easy to use like an MCU." The following benefits can be expected from the large-capacity built-in RAM, which is one of the major features.
In addition, Renesas' proprietary Dynamically Reconfigurable Processor (DRP) technology is used to achieve more than 10 times the image processing performance with lower power consumption than general-purpose microcomputers with ARM cores from other companies. In addition, evaluation kits and various libraries are available, so even beginners can easily start development.
Advantages of using RZ/A2M MPU
- No external RAM required
- BOM cost reduction
- Board area reduction
- Reduction of design burden

Overview of RZ/V2M
RZ/V2M is a product for vision AI that realizes real-time human and object recognition in embedded devices, equipped with Renesas' proprietary AI accelerator "DRP-AI" and a 4K compatible image signal processor (ISP). .
The high power efficiency of "DRP-AI" enables high-speed AI processing with low power consumption, which is essential for embedded devices. "DRP-AI" has 3.6 times the power efficiency compared to GPU. Also, since a heat sink is not required, a reduction in BOM cost can be expected.
