SOPC Builder Components WITHOUT a NIOS?

Altera_Forum · ‎01-09-2006

I was under the assumption that you could use some of the SOPC builder components without a NIOS. For example if I wanted an SPI interface to my FPGA logic I could create an SPI to Avalon bus interface in SOPC builder and use it in my design. Is this true?

Yes, but you will have to provide a bridge between your external logic and the

Avalon bus. This is normally a slave interface to your external logic (e.g. a slave

for your external CPU bus) and a master for the Avalon bus.

I went to one of Altera's seminars (got the nice T-shirt as well :-) )where they demo-ed in detail how to connect external devices and CPUs to the FPGA, using SOPC builder, without using NIOS. So yes it is possible.

You could do weird and wonderful things like connecting an 8051 to SDRAM or giving it 10 serial ports.

Yes, you also have to connect it as a slave or master. Slave is easy, master more tricky.

Hi Victors.

I'm a beginner with Nios II and Quartus II. My developing board mounts a Cyclone II FPGA EP2C35.

I must interface an external Camera (C3088 made of Omnivision OV6620 sensor) with that board but, i don't know how to do that. I mean, the connection to PROTO1/PROT2, it's ok, but how create the interface with the internal system?Should i use Avalon MM? I have look to Portable Reference Board project but is really hard to understand.

Can you give some advices about what you learn on seminary?

Many thanks

Paolo
