Features Benefits I

• Powerful
• Microkernel Architecture designed for
  embedded systems
• Designed for single-CPU and multi-CPU targets
• True real-time performance and small
  footprint
• Includes MQX Host Tools

3
Features Benefits II

• Flexible
• Delivered in full source
• Enables MQX Embedded Stacks, Networking
  Components,and Platform Enhancements
• Tightly Integrated
• Task-Aware Debugging with MetaWare and
  CodeWarrior tools
• Proven
• Shipping in thousands of designs

4
New Features

• Multiple memory pools
• MMU support
• Higher resolution for timers
• Lightweight components
• Task restarts
• Callout futions

5
Advantage I

• Small
• ? MQX RTOSs small size conserves memory space
  and reduces power consumption.
• Portable
• ? The MQX RTOS supports popular embedded
  architectures including ARC.,ARMR, Freescale.
  68K/ColdFire., IBMR/Freescale./AMCC PowerPC.,
  MIPSR and Intel XScaleR
• ? Supports single-processor and mutiprocessor
  designs

6
Advantage II

• Configurable and Scalable
• ? The minimum RTOS configuration requires only 8
  of 25 available components other components are
  linked in only if used by the application.
• High Performance
• ? Time-critical services have been optimized for
  speed and deterministic performance, ensuring
  fast context switch and low-level interrupt times

7
What can be configured?

• Processor register file type and size,
  interrupts, endianness, reset state
• Caches I and/or D, size, ways, line length
• Closely Coupled Memory I and/or D, size
• Additional instructions many optional general
  purpose and DSP instructions
• ARC XY Advanced DSP subsystem memory size,
  banks, ports
• Timers
• Bus BVCI, AMBA/AHB
• Debug JTAG, actionpoints

8
ARC's configurability is the freedom to

• Add components to provide required features
• Add components to increase performance
• Remove unneeded components
• Configure components for maximum efficiency in a
  specific application

Memory Management

• Default variable sized memory allocation and
  de-allocation
• A simpler lightweight memory manager
• MQX offers fixed size buffer management an
  partitions component
• MQX supports the use of multiple memory pools to
  allow separate control of on-chip and off-chip
  memory resource

13
Processor and Board Support

• MQX RTOS is currently available on a full range
  of leading 32-bit embedded processors, including
  ARC, ARM, ColdFire, MIPS, and PowerPC
  processors from ARC, Atmel, AMCC, ARM. Freescale,
  Cirrus Logic, IBM, Intel, Oki, Phytec, and
  Samsung, among others.
• Board Support Packages are available for
  evaluation, development and production boards
  from processor suppliers, ADI Engineering,
  Analogue Micro, Avnet, Arrow, Embedded Planet,
  Logic Product Development, and TQ Components,
  among others.
