我们的应用层软件会使用高阶的卡尔曼滤波，涉及到大量的向量运算（矩阵乘法，求逆等），请问TC3XX，TC4XX芯片对向量运算有硬件加速的支持吗？

例如使用5阶卡尔曼滤波，那么在有硬件加速的前提下，会占用多少硬件资源呢？

For TC2/3xx, please access docs of AURIX™ DSPlib:
– Distributed through Infineon MyICP:
https://myicp.infineon.com/SitePages/Home.aspx

– Delivered as a zip file : AURIX_DSPlib_0v91.zip
– This release includes:
– Application Note AP32528 –Getting started with DSPlib
– Quick Start Guide
– Release Notes
– Overview of the implemented functions
– The DSPlib 0v91 source code to be integrated in your project
(TC2xx/TC3xx) + function examples
– An up and running DSPlib project implemented for a TC39x B-step device board

For TC4xx, please contact your Infineon representative for consult. There is PPU for this purpose, and i.e. for Karman Filter function, TC4xx could give 7x-14x speed increase.
