Nested Interrupts

Rule 2 and Nested Interrupts

If your system allows interrupt routines to nest, that is, it a higher-priority interrupt can interrupt a lower-priority interrupt routine, then another consideration comes into play. If the higher-priority interrupt routine makes any calls to RTOS functions, then the lower-priority interrupt routine must let the RTOS know when the lower-priority interrupt occurs. Otherwise, when the higher-priority interrupt routine ends, the RTOS scheduler may run some other task rather than let the lower-priority interrupt routine complete. Obviously, the RTOS scheduler should not run until all interrupt routines are complete.

Research and Development

With a focus on R&D, Micromagine embedded software engineers go far and wide exploring the breadth of capabilities and fields of application for the next generation of industry hallmarks, identifying the potential pockets of growth for our customers.

Some of the latest examples of our R&D include studying and testing Android OS porting to custom hardware platforms and trying new dimension technologies such as motion controller in game development.

Embedded System Expertise

Deep experience across multiple embedded platforms (ARM Cortex M series, ARM64/aarch64, Intel x86-64)
Custom device driver design and implementation (Linux or microcontroller or otherwise)
Video- and audio-rate (or higher), low-latency DSP algorithms
Multi-threaded applications and data processing
Rapid prototyping

Quality Assurance

Quality Assurance of embedded systems is also available as a separate service for our clients. We provide testing and debugging for a range of embedded solutions.

To craft efficient, resilient, and infallible software, we’ve established two focused QA Labs: Firmware & Embedded QA Lab, and Mobile QA Lab, which are applicable during unit, integration, system, and acceptance testing.
