Transactional Synchronization Extensions
(Intel
®
TSX-NI)
Intel
®
Transactional Synchronization Extensions (Intel
®
TSX-NI) provides a set of
instruction set extensions that allow programmers to specify regions of code for
transactional synchronization. Programmers can use these extensions to achieve the
performance of fine-grain locking while actually programming using coarse-grain locks.
Details on Intel TSX-NI may be found in Intel
®
Architecture Instruction Set Extensions
Programming Reference.
Note: Intel TSX-NI may not be available on all SKUs.

®
Processor Trace
Intel
®
Processor Trace (Intel
®
PT) is a new tracing capability added to Intel
Architecture, for use in software debug and profiling. Intel PT provides the capability for
more precise software control flow and timing information, with limited impact to
software execution. This provides enhanced ability to debug software crashes, hangs,
or other anomalies, as well as responsiveness and short-duration performance issues.
Intel VTune™ Amplifier for Systems and the Intel System Debugger are part of Intel
System Studio 2015, which includes updates for new debug and trace features on this
latest platform, including Intel PT and Intel Trace Hub.
