There is the E subspecification of the RISC-V specification with 16
registers.  I don't know if anybody has implemented this.

The CH32V003 uses it and is of some interest as a Forth target.  It has
16k of flash and 2k of ram.

More efficient in code size.  In instruction execution, typically the
same speed.

https://dl.acm.org/doi/10.1145/3578360.3580261 indicates some minor
speed differences, not always favorable.
