| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. In computer
performance, the Instruction path length is the number of machine code
instructions required to execute a section of a computer program. The
total path length for the entire program could be deemed a measure of
the algorithm's performance on a particular computer hardware. The path
length of a simple conditional instruction would normally be considered
as equal to 2, one instruction to perform the comparison and another to
take a branch if the particular condition is satisfied. The length of
time to execute each instruction is not normally considered in
determining path length and so path length is merely an indication of
relative performance rather than in any sense absolute. |
