Energy Micro EFM32
ThreadX for ENERGY MICRO EFM32
Highlights
The ENERGY MICRO EFM Gecko family of 32-bit Flash Microcontrollers is based on the breakthrough ARM Cortex™-M core - a core specifically developed for embedded applications. The ENERGY MICRO family benefits from the Cortex-M architectural enhancements including the Thumb-2 instruction set to deliver improved performance with better code density, significantly faster response to interrupts, all combined with industry leading power consumption.
ThreadX supports ENERGY MICRO’s EFM32 family of ARM Cortex-M-based 32-bit microprocessors Complete ARM Development Tool Support with IAR EWARM, ARM/RVDS, Keil, GNU Reasonable pricing No Royalties Complete ANSI C source code Easy to use and powerful services Responsive Technical Support Unlimited Threads, Queues, Event Flags, Timers, Semaphores, Mutexes, Block Pools, and Byte Pools Flexible memory usage Timeout available on all thread suspension Advanced preemption-threshold technique Low-overhead Application Timers Size scales automatically Picokernel architecture for size and speed Small footprint (as low as 2 Kbytes) Fast Execution (0.9us context switch@72MHz)
Improve Your Cortex-M Development
Let our extensive experience with the ARM Cortex-M microprocessor architecture help your product development. ThreadX, our high-performance real-time kernel, helps improve your product's quality and its time-to-market. In addition, using ThreadX makes it easier to enhance your product in the future.
Cortex-M Optimizations
ThreadX optimizes context switching on the ENERGY MICRO EFM32 processors to take advantage of the SVC and PendSVC interrupts built into the Cortex-M architecture. This provides low interrupt latency and low overhead due to the unique “tail-chaining” capability of the Cortex-M. As with all ThreadX versions, the full register set is saved only if thread preemption is required.
Nested Interrupt Handling
By default, ThreadX fully supports nested interrupt handling.
