第三，One YAML = one firmware。关于这个话题，adobe PDF提供了深入分析
此外，A lot of the logic area turns out to be consumed by the shifters needed to handle the flexibility of the pin mapping options. A look at the PINCTRL register reveals four “base” selectors which implies four 32-bit barrel shifters, plus a configurable run-length tacked onto the end of the shifters. Basically, the “rotate + mask” portion of the PIO consumes more logic area than the state machine itself, and having to smash a set of rotate-masks + clock division and FIFO threshold computations into a single cycle is quite expensive time-wise. The flexibility of the PIO’s options basically means you’re emulating an FPGA-like routing network on top of an FPGA – hence the inefficiency.
最后，The total effect marks the absence of
另外值得一提的是，As a result, the PIO, while kind of neat as an abstract mental concept, really bugged me as an implementer. Barrel shifters are expensive in hardware. There’s a lot of wires in a barrel shifter, and I’ve been trained to use wires with deliberation. Furthermore, the custom instruction set is hard to code with, especially with all of the out-of-band settings that can affect instruction execution. Even after spending a couple months writing a lot of PIO code, I still struggled to get things to work on the first try, and I relied heavily on Verilator simulations to debug any custom PIO code (I have no idea what other programmers of the PIO do to debug their stuff. But if anything, perhaps one of the greatest utilities of a PIO re-implementation is you can actually debug your PIO code in simulation using Verilator!).
