    Parallel FIFO components?

    DaGi_900591

      Does anyone have any turnkey 8-bit parallel FIFO components?

       

      My use case is:

       

      - I wish to receive 8-bit data via DMA; I want a component where, every time I poke it via a signal, a parallel 8-bit bus is sampled and pushed onto a FIFO.

      - I wish to send 8-bit data sourced via DMA; I want a component where, every time I poke it via a signal, it fetches an 8-bit value from a FIFO and expresses it on an 8-bit bus.

       

      These used to exist on the old PSoC Sensei blog, but that's now gone. I know that you can't do this using the standard UDB tools and have to resort to low-level hacking via the datapath configuration tools; there are some extremely fuzzy instructions in https://www.cypress.com/documentation/application-notes/an82156-psoc-3-psoc-4-and-psoc-5lp-designing-psoc-creator-compon…  but there's only about a page buried in an appendix. I'm really looking for some turnkey components I can just drop into my design.

       

      (Plea to Cypress: please can we have these in the standard component library?)

       

      Thanks!
