Environment perception restructurable mobile terminal communication processor

Abstract

The invention discloses a mobile terminal communication processor with environment perception and reconfigurable ability, comprising a reconfigurable physical layer unit, a clock manager, a time control unit, a microcontroller, a storage unit, a protocol and perception processing unit, a bus bridge contact, a boundary scan interface, an oscillator, a power management circuit, a high-speed interface for multiple architectures and a bus bridge contact. Datum from exterior are received and self-adaptive transceived by the reconfigurable physical layer unit based on oscillation frequency providedby the oscillator and delivered to the external bus after modulated. The processed datum are delivered to the external bus and sent out from the unit. The invention has the advantages that external environment can be sensed and self-adaptive adjustment of a modulation and demodulation technique and a radio frequency amplifier can be realized; the communication between a non heterogeneous and a heterogeneous network is supported; seamless communication with chips of other protocols in a wide area network can be carried out, and the cost of realization is reduced on basis of improved integral performance of the processor.

Description

technical field [0001] The invention relates to the field of computer network communication and integrated circuits, in particular to an environment-aware and reconfigurable mobile terminal communication processor. Background technique [0002] At present, the development of integrated circuits is very fast, and they are more and more used in the communication field. The information and communication society is moving towards an ecological environment of AUN (Ambient Ubiquity Network). The three representative regions of the Asia-Pacific, the European Union, and North America have formulated clear promotion policies and development plans from the perspective of national industries. The next five years will be a critical stage for the popularization and improvement of environmental awareness ubiquitous networks. Ubiqui tous (ubiquitous) is derived from Latin and means to exist everywhere (existing everywhere). In 1991, computer scientist Mark Weiser of Xerox Labs first prop...

AI Technical Summary

Problems solved by technology

[0004] 1. The chip cannot perceive the external environment and make adaptive adjustments to the internal structure

[0005] 2. It can only support 802.11a / b / g protocols, and cannot communicate seamlessly with chips of other WAN protocols

[0006] 3. The chip only focuses on PHY and MAC, and basically does not consider higher-level protocols

[0007] 4. The frequency range generated by the frequency synthesizer is too small to realize scanning in the wide frequency domain according to the spectrum scanning mechanism defined by the developer

[0008] 5. The precision and number of digits of the digital-to-analog / analog-to-digital converter cannot be adjusted, which causes a waste of resources for some low-demand applications
