Introduction to AMBA 4 ACE and big.LITTLE Processing Technology
This paper focuses on the AMBA® ACE and ACE-Lite interfaces, which introduce system-level coherency, cache maintenance, distributed virtual memory (DVM) and barrier transaction support. It is used for multi-core processor systems to enable big.LITTLE™ software to run effectively, increasing system efficiency.
Quality of Service in ARM Systems: An Overview
Nearly all performance-oriented SoCs are dependent on high bandwidth and low latency external memory systems to deliver within cost and performance constraints. This paper goes through the QoS functions that help deliver predictable performance in ARM® systems.
QoS for High-Performance and Power-Efficient HD Multimedia
Ensuring the demands of video streaming are consistently met while minimizing cost and maximizing battery life are the challenges for today's SoC designer. This paper explores how QoS mechanisms can enable lower latency while maintaining sufficient overall system bandwidth.
Introduction to QoS Virtual Networks (QVN)
This white paper explains a new mechanism for reducing the congestion in systems via QoS Virtual Networks. QVN makes system latency and bandwidth deterministic and predictable; preventing blocking in the interconnect by ensuring that a transaction can be accepted before it’s initiated.
