+## General notes about the CH32V003.
+
+CPI/Processor Speed:
+
+Ignoring branches and load/stores, compressed instructions run at 1 CPI. Non-compressed instructions run at 1 CPI for the first 2 instructions, then further ones take 2 CPI regardless of how many more you have.  Running from RAM and running from FLASH have slightly different performance characteristics depending on wait states that should be measured in-situation.
