I built it from examples that i saw. there are hooks from the spi to the onboard memory, so i assume that the spi reads will go into memory somewhere.

If you provide a link or attach the example(s), someone will be able to comment/explain on what that example is doing. But the Altera SPI core does not by itself implement any access to memory. It relies on either your software or a DMA controller to perform those transfers from it's peripheral registers.

My question is how do i know what addresses the spi uses in the onboard memory to store rxdata? And, how do i guarantee that successive spi write of 2 bytes dont just keep overwriting each other, but instead, get their own spot in memory?

Unless you're trying to do something more sophisticated from the example your following, managing the storage of the SPI data is up to your software program: you just need to allocate/reserve a block of memory and place the samples there yourself.
