The Super FX has two Pixel Caches: a primary and secondary.
Each pixel cache has a 64-bit main buffer, which holds 8 pixels, and an 8-bit "bit-pend flag" buffer. The bit-pend flags indicate whether the data in the main buffer is valid.
The primary pixel cache is written to by PLOT.
The Super FX patent contains a block diagram of a single color matrix element in figure 8B. [2]
