ARM Unveils New AMBA System IP products

Major upgrades and new products enable rapid deployment of Cortex and Mali processors into media rich, web-enabled systems

ARM today
announced the launch of new system IP products from the ARM AMBA family:
the AMBA Network Interconnect with Advanced Quality of Service, a new
Dynamic Memory Controller, and the Verification and Performance
Exploration tool.  These significant additions to the AMBA family
further accelerate ARM Partners’ time to market for lower power, higher
performance ARM processor-based SoCs.  

The AMBA Network Interconnect (NIC-301) with advanced QoS (QoS-301) delivers the richest media experience from ARM Cortex CPUs, Mali™
GPUs and Video processors and is optimized to balance low latency with
guaranteed bandwidth.  Interconnect QoS boosts web browsing performance
by up to 30 percent, providing consumers with enhanced responsiveness,
considerably reducing the time taken from click to view. 

The
widely licensed AMBA Dynamic Memory Controller (DMC-342) family has
been extended to support LPDDR2 memories with their higher bandwidth,
lower power and reduced pin-count characteristics.  The DMC-342 manages
memory power modes to reduce system level power consumption. QoS-based
traffic management within DMC-342 optimizes the efficiency of shared
memory access, servicing high bandwidth GPUs while meeting maximum
latency guarantees for real-time masters.

The new AMBA
Verification and Performance Exploration (VPE-301) tool enables the
creation of ‘what if’ scenarios to explore the performance of
subsystems comprising ARM Cortex processors, Mali GPUs and customer IP
prior to software or silicon availability. VPE-301 substitutes RTL with
components that generate statistical AMBA AXI™ traffic profiles, and
has been proven to reduce simulation times by more than 90 percent
while maintaining data-path accuracy. With VPE-301, system architects
can evaluate many more design configurations, ensuring they reach a
solution with optimal performance.

"The drive to constrain
product costs and power consumption represents a major challenge for
system designers, particularly with external memory bandwidth," said
Michael Dimelow, director of marketing, Processor Division, ARM. "To
increase performance, designers need to focus on the efficient use of
this memory bandwidth.  This drives the need both for system IP that
intelligently manages traffic between the masters and memory
sub-system, and tools that aid analysis of the system dynamics ahead of
silicon."
