This NXP real-time control embedded software libraries – RTCESL (former
Freescale embedded software libraries – FSLESL) is a group of
algorithms ranging from basic mathematics operations to advanced
transformations and observers, which can be easily incorporated into complex
real-time control applications, and used in our motor control reference
designs. The algorithms help to speed development and ease of use in
applications that require intensive math computation and control, such as
advanced high-efficiency motor control and power conversion.
The libraries are highly optimized, tested on our hardware and are easy to use
as they are implemented with a C-callable function interface. If the device
has a hardware accelerator for specific calculations like Memory-Mapped
Divide and Square Root Module (MMDVSQ) in some Cortex® M0+ core
based devices or PowerQuad (PQ) hardware accelerator in some Cortex® M33 core-based devices the RTCESL can process some algorithms using such hardware
accelerators to provide quicker calculations. The functions have been tested
against NXP's reference models in MATLAB.
The up to date version of the libraries is available on NXP GitHub.
