ARM-ECS Research Center

The industry-University Centre was founded in 2008 following successful research collaboration over a number of years prior between Prof Al-Hashimi's research group and ARM (Cambridge). The centre is based at Electronics and Computer Science (ECS), University of Southampton, but its researchers work at ARM or at ECS with internships at ARM. It is Co-directed by Prof-Al-Hashimi, and Dr David Flynn (ARM Fellow, Visiting Professor at ECS). The centre focuses on leading-edge research on advanced design methods, architectures and their practical validations for energy-efficient and dependable single-core and multi-core processor systems.
Currently PhD research projects are being carried out in the Centre, funded by ARM, EPSRC and the University of Southampton. Each project has a one or more industrial mentors from ARM in addition to the academic supervisors from ECS. Some PhD students are based at ARM, and others are based at ECS, and typically each student spends three months interning at ARM each year.

EPSRC grant: Resilient and Testable Energy-Efficient Digital Hardware - Saturday, September 1, 2012

EPSRC has agreed to fund research for 3 years on Resilient and Testable Energy-Efficient Digital Hardware. The research will be undertaken in collaboration with ARM, Cambridge.

Machine Learning for Multicore Power Management

There is an increasing complexity in applications. Even with the power management methods like DVFS in place, if an application causes the processor to perform poorly, that will have a negative effect on power utilization.

IP Watermarking of Embedded Processor Cores

The technology scaling allows complex systems to be placed on a single die.  To tackle this complexity it is increasingly desirable to source sub-systems, such as CPUs, from external Intellectual Property (IP) suppliers. The risk of unauthorized use has become critically important to IP vendors. Although methods for securing an IP exist, they often do not provide physical protection and EDA tools are far from universal and pain-free. As a result, auditing the presence of IP in finished products is an important challenge for IP providers.

Quality of Service and Quality of Experience Aware System Level Design

As computers are moving from the traditional large scale designs to smaller, more tightly integrated Systems-on-Chip (SoC), the complexity and the variety of applications are increasing. The IP blocks are connected using a Network-on-Chip (NoC), which employs measures to provide Quality-of-Service (QoS) guarantees for the traffic flowing though the network. Each application places specific demands on both the IPs in the SoC and the interconnect; these demands change as the running applications change.

Dependable Embedded Processors

Leakage power is a major contributor to the IC power consumption in modern electronics design. In many applications processor spend significant amount of time in idle mode. Due to the exponential relationship between leakage power and supply voltage, Idle circuit power reduction can be achieved through voltage scaling. However the reduction in supply voltage can impact the system reliability. The objectives of this work are:

Adaptive Power Management for Multicore Systems
  • Power management policies exist, but these typically reduce performance or result in small power savings
  • As some components in the system may be unused or clocked at higher frequencies than needed, some power savings can be achieved
  • Energy saving opportunities can be found using adaptive Power Management HW for low-level control, without penalising overall performance
  • The strategy for the design is to have low-level, localised Power Management per core
  • Machine Learning is at HW (low-level control, fast response)
Leakage Power Minimisation for Embedded Processors

In a large number of pervasive computing examples such as wireless sensor nodes, RFID or personal health care/monitoring, an electronic device is deployed in the field and can be expected to operate without maintenance forever. The constraint imposed by battery life has resulted in energy harvesting being increasingly used as a method to power a device by scavenging ambient energy from the environment. However, low energy availability results in an energy harvesters output power being severely constrained demanding both high energy efficiency and very low power from the electronics.

Low-Power, High Performance Memory Architectures for Vector Processing

This project aims to improve the energy efficiency of the next generation of high performance ARM processors (A15+). The current focus is improving battery lifetimes under heavy workloads such as gaming and video streaming.  In current systems the cost of moving data to the processor is approximately 100,000 cycles from mass storage (hard disks), 250 cycles from main memory, 10-15 cycles from level 2 cache and 1-2 cycles from level one cache. This project aims to improve the efficiency and speed of the processor - L1 interface.
