the adc should be able to work well for this kind of applications?

I've been trying to process speech on a stm32f407ve development board for some time now, which makes me wonder if the adc is really set up to precisely sample the values. CMSIS FFT Functions. But when...

Other core's view after writing ICC_SGI1R_EL1 to trigger SGI

For example, the codes are executed in core0. codes: (1) send SGI to core1 ICC_SGI1R_EL1 (2) set(a) = 1 i) Then the core1 will first see the irq or the change of variable a? ii) If I add ISB...

What works as a data memory barrier?

We have a section of code that increments a variable shared among several threads. The code section is protected by a ldxr/stxr/dmb spin lock, and there is another dmb after the shared variable is updated...
