RM57L843: Digital signal processing

Hello Marcio,

Yes, you can use the SIMD instruction on RM57 device. The Cortex-R4 processor implementation uses the ARM DSP SIMD instruction set and floating-point hardware to enable fully the capabilities of the Cortex-R4 processor for signal processing algorithms.
