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
The CMSIS-DSP is containing Neon implementation of the f32 biquads. For df2T version, the initialization of the filter is done differently than for the Cortex-M versions.
