# CMSIS-View {#mainpage}

**CMSIS-View** equips software developers with methodologies, software components, and utilities that help to analyze operation of embedded software programs on devices with Arm Cortex-M processors.

Key elements of CMSIS-View are:

 - **Event Recorder** is an embedded software component that implements functions for event annotations in the code.
 - **Exception Fault Analysis** provides functions to store, record, and analyze exception fault information.
 - **eventlist** is a command line tool for processing Event Recorder log files.

## Access to CMSIS-View

CMSIS-View is actively maintained in a GitHub repository and is released as a standalone package in CMSIS-Pack format.

 - [**CMSIS-View GitHub Repo**](https://github.com/Arm-Software/CMSIS-View) provides the full source code of CMSIS-View software, example projects and documentation.
 - [**CMSIS-View Documentation**](https://arm-software.github.io/CMSIS-View/latest/) explains how to use the library and describes the implemented functions in details.
 - [**CMSIS-View Pack**](https://www.keil.arm.com/packs/cmsis-view-arm/versions/) delivers CMSIS-View firmware components and examples in [CMSIS-Pack format](https://open-cmsis-pack.github.io/Open-CMSIS-Pack-Spec/main/html/index.html).

## Key Features and Benefits

 - CMSIS-View enables visibility into the dynamic execution of an application with minimal memory and timing overhead.
 - Works on all Cortex-M devices with only simple debug adapters necessary.
 - Compiler agnostic implementation allows simple integration in application projects.
 - Events are captured with accurate time-stamps.
 - Event Statistic functions allow you to collect and analyze statistical data about the code execution.
 - Enables RTOS-aware debug for CMSIS-RTX and CMSIS-FreeRTOS.
 - Provides logging capabilities for use in regression tests on Arm Virtual Hardware FVP models ([via semihosting](https://arm-software.github.io/CMSIS-View/latest/er_use.html#er_semihosting)).
 - Natively supported in [Keil MDK uVision IDE](https://developer.arm.com/documentation/101407/0538/Debugging/Debug-Windows-and-Dialogs/Event-Recorder).
