The patented technology, called "eFUSE," combines unique software algorithms and microscopic electrical fuses to produce chips that can regulate and adapt their own actions in response to changing conditions and system demands. By dynamically sensing that a chip needs a "tune-up," eFUSE can alter the configuration and efficiency of circuitry to enhance performance or avoid a potential problem. This autonomic capability is expected to change the way chips are designed, manufactured and integrated into computers, cell phones, consumer electronics and other products. If an imperfection is detected, this innovative technology "instinctively" initiates corrective actions by tripping inexpensive, simple electrical fuses that are designed into the chip at no additional cost. The activated fuses help the chip control individual circuit speed to manage power consumption and repair unexpected, and potentially costly flaws. If the technology detects that the chip is malfunctioning because individual circuits are running too fast or too slow, it can 'throttle down' these circuits or speed them up by controlling the appropriate local voltage.

Fast, Powerful but Cheap, and Lots of Control These motivations point to three major objectives for a power conscious embedded processor. Such a processor must be capable of high performance, must consume low amounts of power, and must be able to adapt to changing performance and power requirements at runtime.

The objective of this seminar is to define a micro-architecture which can exhibit low power consumption without sacrificing high performance. This will require a fundamental shift to the power-performance curve presented by traditional microprocessors. Additionally, the processor design must be flexible and reconfigurable at run-time so that it may present a series of configurations corresponding to different tradeoffs between performance and power consumption.

In addition to exploring several mechanisms to fundamentally improve performance, the MORPH project brought forth the idea of "gear shifting" as an analogy for run-time reconfiguration.

Realizing that real world applications vary their performance requirements dramatically over time, a major goal of the project was to design microarchitectures which could adjust to provide the minimal required performance at the lowest energy cost.

The MORPH project explored a number of microarchitectural techniques to achieve this goal, such as morphable cache hierarchies and exploiting bit-slice inactivity. One technique, multi-cluster architectures, is the direct predecessor of this work. In addition to microarchitectural changes, MORPH also conducted a survey of realistic embedded applications which may be power constrained.

Also, design implications of a power aware runtime system were explored. IBM unveiled its eFuse chip-morphing technology, designed to enable processors to dynamically adjust themselves in response to problems or systems demands recently. The technology can sense when the chip needs to increase performance or avoid a potential problem, and then can reconfigure the chip to meet the demands by tripping electrical fuses integrated into the chip.

It can monitor and manage power consumption, repair problems and sense changes in demands on the chip. Chip makers can use the morphing technology to alter chips for systems makers depending on the needs of end-users.

Future uses could include autonomic processors that can self-monitor, self-heal and reconfigure themselves dynamically after they've been put into systems. Chip makers can use the morphing technology to alter chips for systems makers depending on the needs of end-users.

Future uses could include autonomic processors that can self-monitor, self-heal and reconfigure themselves dynamically after theyve been put into systems. Electromigration is used to program the fuses without damaging other parts of the chip.

The activated fuses help the chip control individual circuit speed to manage power consumption and repair unexpected flaws. The said technology will ship under the name eFuse, so called because it employs millions of electrical fuses that are built into the chip's circuitry.

Together, the microfuses act as a kind of autonomous traffic control network, responding to the changing demands placed on the microprocessor to switch individual circuits on and off as required. Indeed, "eFuse is part of a built-in self-repair system that constantly monitors a chip's functionality.

If an imperfection is detected, this technology 'instinctively' initiates corrective actions by tripping inexpensive electrical fuses that are designed into the chip. The fuses help the chip control individual circuit speed to manage power consumption and repair unexpected, and potentially costly flaws", says IBM. There's an element of pre-ship tuning, in which IBM allows eFuse to adapt processors for the customer's anticipated application load.

On site, the technology continues to adapt according to ongoing workloads.

So how does is work? Essentially, the system uses the phenomenon of 'electromigration', in which moving electrons - current - transfer momentum to the surrounding crystal lattice. That causes the lattice to vibrate and can ultimately induce changes in the microstructure that in turn cause a circuit to fail - the chip equivalent of a light-bulb filament fusing.

The greater the vibrations, the hotter the circuit and the hotter the circuit gets, the more it vibrates and the more likely electrons are to hit the lattice, imparting more momentum. The activated fuses help to chip control individual circuit speed to manage power consumption and repair unexpected flows.

This phenomena has traditionally been detrimental to chip performance and was avoided even at significant cost and effort.

IBM has perfected a technique that harnesses electromigration and uses it to program a fuse without damaging other parts of the chip. Previous implementations of on-chip fuse technology in the industry often involved rupturing fuses, which had resulted in unwanted performance and reliability problems.
