As a result, pseudo instructions can be defined and implemented yielding very compact special-purpose code.
2.
UMMPS implements the Branch on Program Interrupt ( BPI ) pseudo instruction using a special type of NOP instruction.
3.
The Branch on Program Interrupt ( BPI ) pseudo instruction provides a simple way for a sequence of code to retain control following a program interrupt.
4.
One important feature would be the abstraction of the target processor instruction set, generating to a pseudo instruction set that could be separately defined or mapped to a real machine's instructions.
