Other Related Technologies

In addition to the above technologies, several other system technologies with their own architecture provisions are available from ARM.
  • Debug and Trace
ARM's debug and trace tools enable system developers to quickly debug real-time software, and to trace instruction execution and associated program data at full core speed. The debug and trace offering includes host based tools along with components such as EmbeddedICE, Embedded Trace Macrocell (ETM™), and the latest CoreSight™ technology, which form part of a modern SoC.

  • AMBA®
The AMBA on-chip interconnect is an established, open specification that serves as a framework for SoC designs and IP library development. The AMBA Advanced High-performance Bus (AHB) interface is supported by all many ARM cores and provides a high-performance, fully-synchronous backplane. Multi-layer AHB represents a significant technical advance that reduces latencies and increases the bandwidth available to multi-master systems. Fully compatible with the current AHB specification, Multi-layer AHBTM is supported on the ARM926EJ-S™ core and by all members of the ARM10™ core family.In 2003, ARM announced the launch of the latest AMBA specification, the AMBA 3 AXITM protocol which is targeted at high performance, high clock frequency systems designs and includes a number of features that make it very suitable for high speed, submicron interconnect.

  • ARM Intelligent Energy Manager ARM
Intelligent Energy Manager (IEMTM) technology implements advanced algorithms to optimally balance processor workload and energy consumption, while maximizing system responsiveness to meet end-user performance expectations. The Intelligent Energy Manager technology works with the OS and applications running on the mobile phone to dynamically adjust the required CPU performance level through a standard programmer's model.
