Benchmarking the STM32MP1 IPC between the MCU and CPU
Stupid Projects does some benchmarking the STM32MP1 IPC between the MCU and CPU.
The MCU is an STM32 ARM Cortex-M4 core (CM4) running at 209MHz and the application CPU is a dual Cortex-A7 (CA7) running at 650MHz. Well, yes, this is a fast CM4 and a slow CA7. As I’ve said those two can share almost all the same peripherals and the OpenAMP API is used as an IPC to exchange data between those two.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
