FIFO is 8-deep. I did fail to mention that explicitly in the article, I think. The depth is so automatic to me that I forget other people don't know it. The deadlock possibilities with the FIFO are real. It is possible to check the "fullness" of a FIFO using the built-in event subsystem, which allows some amount of non-blocking backpressure to be had, but it does incur more instruction overhead. |
