- NatureDSP Library for HiFi3 & HiFi3z DSP cores
- The source code is common to both HiFi-3 and HiFi-3Z cores.
- The xws provided supports both HiFi3 and HiFi3z.
- Select the required HiFi-3 or HiFi-3z core for building, in both xws and linux environments.
- Last stable release version of the NDSP contains two xws files.
- An xws each, for the library-kernels and the test-driver. Ex : HiFi3z_VFPU_Library_v4_2_0.xws & HiFi3z_VFPU_Demo_v4_2_0.xws
- Building and executing the xws in Xtensa Xplorer is described in the API Reference Document.
- Building and executing the source code in linux is described in the https://github.com/foss-xtensa/ndsplib-hifi3z/tree/main/doc.
- Detailed release documentation can be extracted from lib.xws/doc folder.

Release Date : Mar 2024
-
The source code has been updated to make it compatible with RJ-2024.3 tool chain.
-
Verification & testing has been done with a very limited number of HiFi-3 and HiFi-3z cores, RJ-2024.3 tool chain (LX8.0.3).
-
Sanity testing has been done for backward compatibility on xt-clang using RI-2023.11 tool chain (LX7.1.10) cores.
-
Known issues:
- For dct functional regression in both -brief and -full, the test vectors are picked up from the sanity folder.
- This contains the source code (NDSP_HiFi3_v420.zip) along with make files that will build in linux environment.
This contains help documentation on how to build the source code in linux and run the performance and functional regressions.
