More details about the hardware accelerator in stm32h730vb ?

[2217335612]

stm32h730VB，Mathematical acceleration • CORDIC for trigonometric functions acceleration • FMAC: Filter mathematical accelerator

​

Are those mathematical accelerations fixed-point or floating-point ? 32bit or 64bit ?​

[Danish1]

Cordic is fairly well described in the Reference Manual for stm32h730.

I haven't used it, but a quick glance tells me that the numbers are fixed-point, either q1.31 or q1.15

FMAC again looks to be fixed-point, q1.15 input, q4.22 output

(Edit: On first reading, I only answered cordic)

Hope this helps,

Danish

Thanks, Danish. So, for the high-accuracy computation, should we use the floating-point unit instead of those hardware accelerators ?

Obviously going to depend on the type of math and computations you plan on doing, and the number space/range in question.

T​he MCU has a pretty well functioning double-precision FPU, which is better suited to non-DSP oriented tasks.
