I know that it is possible with the Avalon Bus. But I dont want to use it. I just want to have access on some signals which will come via SPI- Slave Memory, which runs independent .
Maybe you have an idea :D
Thank you !
he solved it with a dual port ram - but also uses the avalon bus -
it looks like there is no easy way around the avalon bus .. so my spi slave needs to be connected to an avalon interface...
and this guy used PIO - but as he needs to transfer al lot of data he gets problems since one trasfer takes 4us .. or something like this : https://forums.intel.com/s/feed/0D50P00003yySGpSAM?language=en_US
so for my little spi slave it should be maybe enough
Any data transferred to or from NIOS II must use the Avalon bus. If you are targetting fast access you have to know that it isn't the Avalon, it is the approach you use. For example, if you put the data on a flash device will require more time to end the process.
Hi my friends :D
I write it short: It is unusuaal to do this but for my project it is okay for first tests:
SLIDE-SWITCH ->TOPLVL -> Entity TEST-> PIOIN->NIOS->PIOOUT->Entity TEST2 ->LEDs
It worked........ xD
