///
|
|
/// The goal of the summary view is to give a very quick overview of the
|
|
/// performance throughput. Below is an example of summary view:
|
|
///
|
|
///
|
|
/// Iterations: 300
|
|
/// Instructions: 900
|
|
/// Total Cycles: 610
|
|
/// Dispatch Width: 2
|
|
/// IPC: 1.48
|
|
///
|
|
///
|
|
/// The summary view collects a few performance numbers. The two main
|
|
/// performance indicators are 'Total Cycles' and IPC (Instructions Per Cycle).
