Description
This investigation consisted of analyzing the source code of
one of the IBM Series/1's operating systems, the Event
Driven Executive, and one of its Application Program
Products, the Multiple Terminal Monitor, for combinations of
existing hardware mnemonic instructions. Such instructions
could possibly be vertically migrated into new single
mnemonic hardware instructions, thus improving system
performance. Two pairs of instructions were found which
seem to be strong candidates for such vertical
migration. Many instructions available on the Series/1 were
not used in any of the modules examined. This suggests that
some hardware instructions could be eliminated.
