    摘要: In a portable electronic device, a method and apparatus for providing a predetermined portion of a limited resource from a programmable resource allocators (PRAs) 240 to a processor 22 to execute a task 210 optimally. The processor 22 programming the PRA with a resource utilization input (RUI) 250 prior to executing the task 210. The RUI 250 stored in a task descriptor 220, and the task descriptor 220 and the task 210 stored in the memory 200.

    摘要: A method and apparatus for reducing power consumption in a portable electronic device (100) with an LCD screen (104) and operating with a CPU (114) switchable between a high power mode and a low power mode. When input commences on a surface of the LCD screen (104), an interrupt signaler (108) generates a first interrupt signal to an interrupt controller (112). Upon receiving the first interrupt signal, the interrupt controller (112) switches the CPU (114) from the low power mode to the high power mode, turning on at least one detection panel (106) coupled to the LCD screen (104) and to an ADC (110). When input ceases on the surface, the interrupt signaler (108) generates a second interrupt signal to switch the CPU (114) from the high power mode to the low power mode, turning off the at least one detection panel (106) and the ADC (110).
