What is Cortex-M series?
The ARM Cortex-M is a group of 32-bit RISC ARM processor cores licensed by Arm Holdings. These cores are optimized for low-cost and energy-efficient integrated circuits, which have been embedded in tens of billions of consumer devices.
What is the difference between ARM Cortex M3 and M4?
Overall, the most noticeable difference between M3 and M4 is the optional single-precision (IEEE-754) Floating Point Unit (FPU) avail- able with the M4. The success or failure of an embedded design often rests on finding the right balance between system performance, energy consumption and solution cost.
What is ARM Cortex microcontroller?
Arm® Cortex®-M in a nutshell The Arm® Cortex®-M group of processor cores is a series of cores optimized for power efficiency and deterministic operation. It is widely used in microcontrollers (MCUs) and can also be found embedded into multi-core microprocessors (MPUs).
Why are there so many buses on the ARM Cortex-M processor?
The Cortex-M3 and Cortex-M4 microcontrollers are designed with a number of parallel internal busses this is called the “AHB bus matrix lite.” The bus matrix allows a Cortex-M-based microcontroller to be designed with multiple bus masters (ie, a unit capable of initiating a bus access) which can operate in parallel.
What are all the factors to be considered when selecting a microcontroller device for a product?
Key factors to consider when choosing a microcontroller
- Power efficiency.
- Temperature tolerance.
- Security.
- Hardware architecture.
- Processing power.
- Memory.
- Hardware interface.
- Software architecture.
Which is ARM Cortex core is right for your application?
The ARM® Cortex® series of cores encompasses a very wide range of scalable performance options offering designers a great deal of choice and the opportunity to use the best-fit core for their application without being forced into a one-size-fits-all solution. The Cortex portfolio is split broadly into three main categories:
