Based on this methodology, Teledyne e2v offers a service that enables the power consumption characteristics of QorIQ® T-Series and P-Series (Power Architecture®), as well as the ARM® based Layerscape devices that are supplied to customers’ systems to be studied in detail, rather than relying only on datasheet information. In a recent safety-critical aerospace customer project, Teledyne e2v was able to deliver T1042 multi-core microprocessors for which the power consumption was almost 50% lower on the final application – thereby dramatically reducing the constraints placed on the overall system.
The high levels of functionality needed by modern embedded designs means that engineers want to fit in as 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. Published parametric data concerning power consumption will have certain margins included (based on device variation and worst case operating conditions). Often these will force engineers to be overly cautious – specifying microprocessors that offer less performance (or running devices at lower frequencies than they can actually attain), to ensure they remain within the maximum power consumption that their system will support.
Drawing on unrivalled knowledge in providing the market with high-reliability processing solutions, plus direct access to the native test programs from NXP (its original microprocessor manufacturing partner), Teledyne e2v is in a unique position when it comes to understanding devices’ power characteristics. By combining all this with accurate replications of customers’ use cases and the actual application conditions that the microprocessors will be subjected to, comprehensive static and dynamic power consumption profiles can be obtained. Consequently, the company goes beyond the margins stated on datasheets and customers can source fully warranted power-optimized hardware.
