Field Programmable Gate Arrays (FPGAs) based on ARM Cortex-M processor cores, also known as Cortex-MO FPGAs, are reconfigurable integrated circuits that combine the flexibility of an FPGA with the processing power and ecosystem of the ARM architecture. Cortex-MO allows developers to integrate custom hardware accelerators while leveraging the efficiency, toolchain and software investments of Cortex-M….

The ARM Cortex-M4 and Raspberry Pi are two very different devices that serve different purposes. The Cortex-M4 is a 32-bit ARM processor core designed for embedded applications like IoT and wearables. The Raspberry Pi is a small single-board computer designed for hobbyists and educational use. While both utilize ARM architecture, the Cortex-M4 offers real-time performance…

The Raspberry Pi uses an ARM-based system-on-a-chip rather than an x86 processor. All models of the Raspberry Pi, from the earliest Raspberry Pi Model B to the latest Raspberry Pi 4 Model B, have used ARM processors. The ARM architecture is very different from x86, offering advantages like reduced power consumption that make it popular…

The Arm Cortex M4 and ESP32 are two popular 32-bit microcontroller units (MCUs) used in a variety of embedded systems and Internet of Things (IoT) applications. Both offer powerful capabilities but have key differences that engineers should consider when selecting a microcontroller for their project. The main factors to compare are architecture, performance, features, development…

The Raspberry Pi RP2040 and Espressif ESP32 are two of the most popular microcontroller units (MCUs) used by hobbyists and engineers alike. Both offer compelling capabilities at affordable prices, but they have some important differences that users should consider when selecting a microcontroller for their next project. Introducing the RP2040 and ESP32 The RP2040 was…

The Cortex-M4 processor, like most modern processors, supports power-down modes to conserve energy when the system is idle. To properly resume from a low-power state, the processor’s context (register contents, stack pointer, program counter, etc.) must be preserved. This article provides an overview of the different low-power modes, reset behavior, and how to save and…
