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.”
All of these products are available for licensing from ARM today.
