Hello everyone. I want to understand the CORDIC engine, using the nucleo-u575zi board. The guide says that the cordic uses data in q1.31 format. Could please someone explain how to convert results into an ordinary int value? And how to convert an int...
I was looking at some slides that I found called STM32H7- CORDIC co-processor (CORDIC, Revision 1.0) and noticed the following on slide 6: According to this, the fractional number being represented by the fixed-point integer bits is (-1)^s multiplied...
Dear STM32 team,I want to thank you, honestly, for a really great MCU chip. Well done.(just as my friendly feedback to you and company)When I say, the STM32U5xx is a really "cool" MCU - I mean two things:It is really cool, in terms of temperature:I a...
Hello,I have a large sample array of 2^22 values, coming from a high speed ADC, and saved in a RAM.I need to perform a FFT on this array. No real time considerations are needed, so the operation can take a while (several seconds for example), no prob...
I am using the CORDIC on an STM32G4 for a project and was curious about the difference in performance based on the compiler optimization level. With no optimizations, LL_CORDIC_FUNCTION_PHASE completed in 113 cycles. With O1 optimizations, LL_CORDIC_...
stm32h730VB，Mathematical acceleration • CORDIC for trigonometric functions acceleration • FMAC: Filter mathematical acceleratorAre those mathematical accelerations fixed-point or floating-point ? 32bit or 64bit ?
Hi,I am trying to use CORDIC in DMA mode in STM32G4 using LL drivers. However, the data from the input buffer is not being transferred to the CORDIC WDATA register. But the data from the CORDIC RDATA register (the initial value zero) is being transfe...
Hi, Are there any examples that use CORDIC with Low-level drivers? Thanks
This is the only µC from the family which has not CORDIC according to the page here:https://www.st.com/en/microcontrollers-microprocessors/stm32g4x1.html#productsIs this true? why is this the only from the family to not have cordic function?
