Very much looking forward to play with the BIO functionality on the Baochips that I have ordered. Thanks for the nice write up! It is fascinating to see how widely applicable the "just throw a RISC-V core or 4 in there" design pattern is. The wide range of CPU designs that are standardized, the number oc mature open source implementations, and the lack of royalty fees, and the ready-to-run programming toolchains really drives this to a new level. And CPUs are small in die area anyway compared to SRAM! Was cool to see on the RPI2350 how they just threw in another two RISC-V cores next to the ARMs.

For these reasons specified above, I think that this trend will continue. For example, in my specialization of edge machine learning, we are seeing MEMS sensors that integrate user programmable DSP+ML+CPU right there on the sensor chip.
