greg samsa Posted August 21, 2014 Report Share Posted August 21, 2014 Hi All,I've been getting back into some Papilio development again lately and have been very happy to see all the improvements to the SoC ecosystem. I've been able to reproduce the pwn tutorial (very helpful!) and now want to add a toy 'adder' (add two registers and store the result in a third) component. I'm struggling to understand the behavior of async vs sync from the perspective of software running on zpuino. With an async result do you poll for a ready bit, vs having the cpu block on sync? Are there software examples of the two, or best practices to follow? The default template is async, and the vhdl code makes sense, I'm just wondering… for the adder component described above, should I be using sync? (I've seen the examples of that in another thread). Thanks in advance,-Greg Quote Link to comment Share on other sites More sharing options...
