In a sense, most processors that could run a full Java installation
already have what they need.

In many case, range limited integer checking can be done at compile
time, because of the greater precision. Suppose, for example, you are
adding two one digit numbers. If each of them is in a [0,9], the
compiler knows that the result will fit in a [0,18]. If each is in a
byte, the compiler cannot know that their sum fits in a byte.

In the remaining cases, we are looking at comparisons involving
constants and values that are already in registers, and conditional
branches that go the same way somewhere between 99.9999% and 100% of the
time. The expensive operations are cache misses and mis-predicted
branches, and neither is likely in this case. The processor in a small
2011 PC is a supercomputer by historical standards, with the ability to
do multiple operations at the same time, if the data is available.
