MQX RTOS License Types
As described below, the MQX RTOS can be licensed for use on ARC processors in one of two ways - using our standard private commercial fee-based licensing terms or via a new no-cost, ARC Community Source License (ACSL) where licensees provide back their modifications and configurations of the MQX RTOS to ARC as part of the ACSL terms.

ACSL Non-Commercial License
This license allows the internal use of the MQX RTOS for research, evaluation, development or testing by the licensee. This license does not permit shipping of a commercial product using the MQX RTOS. Source code and ownership of modifications, bug fixes, derivative products and extensions for all changes made by the Licensee must be contributed back from the Licensee to ARC. No fees are required for this license type however no warranties are provided, and no support or maintenance is available.

Private License
This license allows the MQX RTOS to be utilized in development and then deployed inside a specific licensee product. Source code and ownership of modifications, bug fixes, derivative products and extensions for all changes made by the Licensee are NOT required to be contributed back from the licensee to ARC and remain private with the Licensee.
The MQX RTOS can be used in development and then deployed as a linked component of a binary executable inside a specific customer product. Licensing fees are required for each customer product using the MQX RTOS under this type license but no run-time per-unit royalties are required. Multiple products can be licensed using special multi-product licenses at discounted rates.
When the MQX RTOS is licensed using the private license, licensees can purchase and receive support and maintenance directly from ARC International's customer support team.
MQX RTOS private licensees can download product releases and source code from the MQX Community website and the ARC Customer Support website.
