We plan to use in our projekt QN9080. And the question of the speed of data transmission through DMA is key moment for us. In general we have next question: Which max data transfer speed from/to 8-GPIO to/from DMA-RAM excluding all slowing factors (ideally)?
We plan to use the following mode:
1. Update rate 8-GPIO is 32 MHz.
2. CLK_AHB, CLK_GPIO and CLK_DMA is 32 MHz
3. We use only one DMA chanel . Others DMA chanels are disabled.
4. All other peripherals are disabled.
5. We transfer only 1 kb to RAM, and then processed this data.
We plane to use it for transfer from external ADC with clocking frequency 32 MHz.
I plan to use following configure:
1) Can we transfer data without error on speed 32MB/s, if we use this configure?
2) Which configure can we use to transfer data on this speed?
3) Can the chip provide an estimated speed of 32 or 16 or 8 Mbytes / s?
Datasheet and user manual don't contain this information.
Thanks in advanced,
