Abstract:
System comprising at least two integrated processors (P1 and P2). These two processors (P1 and P2) are operably connected via two bi-directional communication channels for exchanging information. For establishing the bi-directional communication channels, the system comprises a first processor bus (10) to which the first processor (P1) is connected, a first direct memory access unit (45), a first programmable unit (34), and a first shareable unit (13). The programmable unit (34) can be programmed by the first processor (P1). Also comprised is a second processor bus (20), the second processor (P2) being connectable to the second processor bus (20), a second direct memory access unit (35), and a second programmable unit (44). Said second programmable unit (44) is programmable by the second processor (P2).
Abstract:
The radio telephone has at least one control processor (10) and at least one signal processor (9), selectively switched into the active state only when required, for reducing the overall energy requirement. A control stage (8) controls the switching of the control processor and the signal processor. At least one of the processors is divided into at least two partial blocks, which can be activated individually by the control stage.
Abstract:
For a terminal for mobile communication which includes a display device it is proposed to save energy by arranging a control device so as to disconnect at least a part of the display device in dependence on a relevant operating state.
