Hi, I am looking at ARM CMSIS code for biquad float32 implementation. This is written for Cortex-M as documentation states. How much effort would be needed to port this code to Cortex-A53? The code should be fast, optimized using intrinsics, not assembly. Thanks.
biquad
Actually it says:The Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for microcontrollers that are based on Arm® Cortex® processors.
But it does not list Armv8-A, but then you did not say whether you want to use AArch32 or AArch64.
Edit: My bad, DSP lib is cortex-m only.
