Low-power oriented microcontroller architecture

A new criterion becomes move and more important in digital design. the power.. Nearby criteria such as size, speed complexity, testability, the power consuming criterion is imposed by the "mobile electronics". On the other. side, the microcontroller technology is involved and will be involved in almost all current solutions offered by electronics. The flexibility of use pf microcontrollers increases if all internal functions are performed by programs. The "virtual peripheral" is the best solution that maintains the microcontroller complexity at a low level. This approach seems to be a contradictory one. Building all the functions by programs wastes power in the standard approach. Our goal is ho offer a solution that satisfies both the flexibility of programed solutions and the low-power,el design criterion. The paper presents power-aware design principles microcontrollers with virtual peripheral, used for programed logic applications.
