naming CPUs

I'm planning a new product line, some little PoE instruments, using
the dual-core Raspberry Pi RP2040 chip. One CPU will do the
communications, math, calibrations, and such, and the other will be
hard bare-metal realtime I/O.

We were debating what to call the two CPUs. Left and Right? Manager
and Realtime? Alice and Bob?

Can't say Master and Slave any more.

We did some timing tests on the 2040 chip. It's awesome, for 70 cents.
