Deploy Linux for Multimedia Applications
For ARC multimedia subsystems based systems with a memory management unit (MMU), ARC offers an optimized port of the Linux 2.6 OS kernel. Features specific to the ARC Linux port are:
- Supports subsystems that include an MMU
- Automatic detection of instruction cache and data cache configuration
- Fast context switching using ARC MMU's multiple address spaces
- Provides Ethernet, IDE and UART drivers for ARCangel 4 development system
- Support for ARC SIMD, DMA and extensions
- Ptrace support for GDB debugging
- Compatible with ARC GNU tools

MQX-EP Software for ARC Processors
MQX Software has helped leading companies bring embedded products to market for nearly 20 years. During this time, developers have come to rely on the way the MQX RTOS and other MQX software products work with their tools to help them keep on schedule. The MQX RTOS offers a highly optimized application development platform for ARC processors designed for speed and size efficiency. The MQX RTOS is at the center of a wide array of MQX software protocol stacks, file systems and other run-time components, all compatible with the MQX RTOS that enhance the capabilities of today's advanced embedded devices. And at less than 6 KB in size, the MQX RTOS is small enough to use instead of a homegrown scheduler while still providing advanced features.
ARC recently updated the MQX product family with the MQX-EP RTOS, optimized for ARC Energy PRO subsystems and cores. MQX-EP adds new features to control power at a fine-grained level, even down to individual threads. MQX-EP contains all of the features of ARC’s MQX RTOS and adds new features that allow software developers to exploit the full power-saving capability of the Energy PRO cores. MQX-EP provides a software API that allows designers to program Energy PRO’s power management unit and optimize the power settings for a given application.
