Texas Instruments' new ROM-based C280x and Flash-based F280x digital signal controllers are optimized for motor control, and are said to be particularly well-suited to such applications as electronic power steering and integrated starter-alternator control. Both processors employ a patent-pending Pulse Width Modulator (PWM) with 150 ps resolution, reportedly making them about 64 times more precise than competing processors. One member of the family the TMS320F2809 offers 256 Kbytes of on-chip Flash and six PWM channels of 150 ps resolution.

Researchers working with additive manufacturing have said multimaterial techniques will allow industry to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
