1.CMSIS Version 5

https://github.com/ARM-software/CMSIS_5

introduction

https://arm-software.github.io/CMSIS_5/General/html/index.html

The CMSIS is a set of tools, APIs, frameworks, and work flows that help to simplify software re-use, reduce the learning curve for microcontroller developers, speed-up project build and debug, and thus reduce the time to market for new applications.

CMSIS started as a vendor-independent hardware abstraction layer Arm® Cortex®-M based processors and was later extended to support entry-level Arm Cortex-A based processors. To simplify access, CMSIS defines generic tool interfaces and enables consistent device support by providing simple software interfaces to the processor and the peripherals.

CMSIS is defined in close cooperation with various silicon and software vendors and provides a common approach to interface to peripherals, real-time operating systems, and middleware components. It is intended to enable the combination of software components from multiple vendors.

CMSIS is open-source and collaboratively developed on GitHub.

2.lisa

https://github.com/ARM-software/lisa

The LISA project provides a toolkit that supports regression testing and interactive analysis of Linux kernel behavior. LISA stands for Linux Integrated/Interactive System Analysis. LISA's goal is to help Linux kernel developers to measure the impact of modifications in core parts of the kernel. The focus is on the scheduler (e.g. EAS), power management and thermal frameworks. However LISA is generic and can be used for other purposes too.

3.Tarmac Trace Utilities

https://github.com/ARM-software/tarmac-trace-utilities

Some Arm products -- usually software models of CPUs -- are able to run in a mode where they generate a detailed trace of a program's execution. These traces are often written to a text file, in a format called 'Tarmac'.

Tarmac Trace Utilities is a suite of tools that can process trace files in Tarmac format.

4.SCP-firmware - version 2.8

https://github.com/ARM-software/SCP-firmware

There is a strong trend in the industry to provide microcontrollers in systems to abstract various power, or other system management tasks, away from Application Processors (APs). The Power Control System Architecture (PCSA) [1] describes how systems can be built following this approach.

The PCSA defines the concept of the System Control Processor (SCP), a dedicated processor that is used to abstract power and system management tasks away from application processors.

Similar to the SCP, the Manageability Control Processor (MCP) follows the same approach with the goal of providing a management entry-point to the System on Chip (SoC) where manageability is required, such as on a SoC targeting servers.

SCP-firmware provides a software reference implementation for the System Control Processor (SCP) and Manageability Control Processor (MCP) components found in several Arm Compute Sub-Systems.

17. CoreSight Access Library (CSAL)

https://github.com/ARM-software/CSAL

The CoreSight Access Library (CSAL) provides an API which enables user code to interact directly with CoreSight devices on a target. This allows, for example, program execution trace to be captured in a production system without the need to have an external debugger connected. The saved trace can be retrieved later and loaded into a debugger for analysis. CSAL can be run on application core or a management core.

coresight是ARM公司提出的，用于对复杂的SOC，实现debug和trace的架构。该架构，包含了多个coresight组件。众多的coresight组件，构成了一个coresight系统。我们也可以根据coresight架构，实现自己的coresight组件。
每个coresight的组件（component），都要遵循coresight架构的要求

The ASTC compressed data format, developed by Arm® and AMD, has been adopted as an official extension to the Open GL®, OpenGL ES, and Vulkan® graphics APIs. It provides a major step forward in terms of both the image quality at a given bitrate, and the format and bitrate flexibility available to content creators. This allows more assets to use compression, often at a reduced bitrate compared to other formats, reducing memory storage and bandwidth requirements.
