Now No Compromising Of Performance For Low Power Microprocessors


Electronics design engineers can benefit by increasing their device performance, along with making enough headroom for further hardware upgrades

For a high level of device functionality, current embedded design engineers want to incorporate much processing capacity as possible. However, in many use cases (particularly in the avionics, military and space sectors), stringent power constraints must also be adhered to. Often this forces engineers to be overly cautious, which makes them go for low power microprocessors while compromising performance.

Thus, to provide maximized performance, Teledyne e2v, one of the leaders for reliable semiconductor solutions, has developed a methodology for its range of microprocessors with the help of which, power consumption characteristics of QorIQ® T-Series and P-Series (Power Architecture®), as well as the ARM® based Layerscape devices can be studied in detail (rather than relying only on datasheet information).

Unmatched performance


With its unrivalled knowledge in providing high-reliability processing solutions, along with direct access to the native test programs from NXP (its original microprocessor manufacturing partner), Teledyne e2v’s understanding of device power characteristics is unmatched. Therefore, accurate replications of customers’ use cases and the actual application conditions that the microprocessors will be subjected to, (static and dynamic power consumptions) can be obtained.

Now, engineers can confidently boost their system performance by procuring only the most power efficient devices for the dedicated application. Other benefits include: creating additional headroom in systems (in order to incorporate further features and functionality at a later stage) and the potential of extending working lifespans.

“When dealing with high-performance multi-core processors, there can be notable variation in static power from one device to another, while clocking frequency and process load will affect the dynamic power. Then there is the operational temperature to consider too,” explains Thomas Guillemain, Marketing & Business Development Manager at Teledyne e2v. “Through the visibility offered by this new service, we are now enabling far better optimization of our 32-bit and 64-bit microprocessors, so that maximum performance can be derived while keeping within the associated power consumption confines.”

In a recent safety-critical aerospace project, Teledyne e2v implemented T1042 multi-core microprocessors whose power consumption was almost 50 percent lower on the final application – thereby dramatically reducing power constraints of the overall system.
