Was watching the Sean video again and noticed something. I'm probs wrong or forgotten but I couldn't recall us doing a lot of focus on MPUs before, mostly MCU other than Microchip Technologys MPU at CES2024.
Sean specifically mentions MPU when discussing Pico, Akida IP & scalability. Whilst Pico obviously suited to the edge in things like a MCU I found it interesting it being discussed within a MPU or maybe I got the wrong context?
Wonder who maybe wants Pico in a MPU & for what end use product given the examples below.

From a website discussing the differences in MPU v MCU.
Microprocessor (MPU) or Microcontroller (MCU)

An MPU is a more powerful and flexible processing unit compared to an MCU. Unlike an MCU, an MPU does not have memory and other parts built into the same chip. Instead, it relies on external components for memory (such as RAM and ROM) and other parts. This setup allows MPUs to offer greater processing power and flexibility, making them suitable for more complex and demanding applications.
The CPU within an MPU is typically more advanced, capable of handling multiple tasks and running operating systems such as Linux or Windows. This makes MPUs ideal for applications that require a lot of computational power, multitasking capabilities, and extensive software support. Examples include personal computers, smartphones, tablets, and high-end embedded systems.
Primary Differences
Feature | MCU | MPU |
Memory | On-chip Flash memory | External DRAM and NVM |
Start-up Time | Fast | Slower due to external memory |
Power Supply | Single voltage rail | Multiple voltage rails |
Peripheral Interfaces | Limited to integrated peripherals | Extensive external connectivity options |
Use Cases | Embedded systems, real-time applications | Complex OS-based applications, high data throughput |
