The Texas Instruments Digital Signal Processing library (DSPLib) is an optimized set of functions to perform common fixed point signal processing operations on MSP430 and MSP432 devices. Applications where processing intensive filters and transforms are needed can leverage the DSPLib to run in real time with minimal energy consumption for ultra low-power applications.
The following tool chains are officially supported:
Added support for MSP430FR2355 and DSPLib functions in ROM.
Updated benchmark functions to support TIMER_B when TIMER_A isn’t available.
Added defines for C std types not defined in C++.
Fixed issue with msp_fir_q15 function not restoring mpy context before returning.
Fixed issue where msp_lea_locked was not inititalized in some instances.
Fixed example code warning for FRAM devices not clearing LOCKIO bit.
Minor updates to API documentation.
Added ROM usage guide.
Updated manifest.

Versioning
This product’s version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and b is an unrestricted set of digits used as an incrementing build counter. To support multiple side-by-side installations of the product, the product version is encoded in the top level directory (e.g. DSPLIB_01_00_00_00). Subsequent releases of patch upgrades will be identified by the patch number, ex. 1.0.1.05 with directory DSPLIB_01_00_01_05. Typically, these patches only include critical bug fixes.
All releases have 4 digits (M.mm.pp.bb). This includes GA and pre-releases (engineering, alpha/EA, beta, etc.). Pre-releases are denoted with a suffix (e.g. 6.30.00.00-eng or 6.30.00.10-beta).
