[[Advanced Micro Devices|AMD]] '''CodeAnalyst''' is a [[Graphical user interface|GUI]]-based code [[Profiling (computer programming)|profiler]] for [[x86]] and [[x86-64]]-based machines. CodeAnalyst has similar look and feel on both [[Linux]] and [[Microsoft Windows]] platforms. CodeAnalyst uses specific hardware profiling techniques which are designed to work with AMD processors, as well as a timer-based profiling technique which does not require specific hardware support; this allows a subset of profiling features to work on non-AMD processors, such as [[Intel]] processors.<ref>{{cite web

As of March 2013, CodeAnalyst has been replaced by [[AMD CodeXL]].<ref>{{cite web

==Code optimization==
CodeAnalyst is built on [[OProfile]] for the Linux platform and is available as a free download. The GUI assists in various kinds of [[profiling (computer programming)|code profiling]] including time based profiling, hardware event-based profiling, instruction-based profiling and others. This produces statistics about details such as time spent in each [[subroutine]] which can be [[Data drilling|drilled down]] to the source code or [[Instruction set|instruction level]]. The time taken by the instructions can be indicative of stalls in the [[Pipeline (computing)|pipeline]] during instruction execution. Optimization could be as simple as reordering the instructions for maximum utilization of a data line cache or altering/removing the [[Branch (computer science)|branches]] and [[Control flow#Loops|loops]] so that the maximum number of execution units(Load/Store units, [[Arithmetic logic unit|ALU]], [[Floating point|FP]] execution unit...) are utilized in parallel.

Support for [[perf (Linux)|PERF]] was added in CodeAnalyst 3.4, allowing users to choose between OProfile and PERF as the profiling backend.<ref>{{Cite web |url=http://developer.amd.com/2012/07/12/amd-releases-codeanalyst-3-4-for-linux/ |title=AMD releases CodeAnalyst 3.4 for Linux! |access-date=2013-11-09 |archive-url=https://archive.today/20131109140717/http://developer.amd.com/2012/07/12/amd-releases-codeanalyst-3-4-for-linux/ |archive-date=2013-11-09 }}</ref>

==Instruction-Based Sampling==
CodeAnalyst supports IBS (Instruction-Based Sampling) that was introduced in Family 10h AMD processors (Barcelona). With IBS support, CodeAnalyst can more precisely identify instructions that cause pipeline stalls and cache misses.<ref>{{cite web|url=http://developer.amd.com/assets/AMD_IBS_paper_EN.pdf |title=AMD Developer Central |publisher=[[AMD]] |date= |access-date=2012-02-14 |archive-url=https://web.archive.org/web/20120214080546/http://developer.amd.com/assets/AMD_IBS_paper_EN.pdf |archive-date=2012-02-14 }}</ref>

==Open-source==
The Linux version of CodeAnalyst is available under [[GNU General Public License]] 2.0.<ref>[http://developer.amd.com/tools/hc/CodeAnalyst/codeanalystlinux/Pages/default.aspx#download AMD CodeAnalyst Performance Analyzer for Linux]</ref>

CodeAnalyst also uses other open-source components, including the [[Qt (framework)|Qt framework]], [[DWARF|libdwarf]], [[Executable and Linkable Format|libelf]], and the [[Binary File Descriptor library]].
