Abstract

The invention discloses a 3G wireless router with a single CPU (Central Processing Unit), relating to the field of wireless routers. The 3G wireless router with the single CPU comprises a WIFI (Wireless Fidelity) antenna (WIFI-RF), a 3G antenna switch (3G-RF), a power management unit (PMU), a WIFI module and a communication processor (CP), wherein the WIFI (Wireless Fidelity) antenna (WIFI-RF) is connected with the WIFI module through signal; the 3G antenna switch (3G-RF), the power management unit (PMU) and the WIFI module are respectively connected with the communication processor (CP)through signal; and the communication processor (CP) comprises an ARM (Advanced RISC Machines) processor, a micro-kernel operating system (VMOS), a real time operating system (RTOS), a general operating system (RichOS), a communication protocol module and an application program module. The invention is free from the traditional double CPU framework of the wireless router, operates the functions of an application processor (AP) on the communication processor (CP), that is to say, the 3G wireless router with the single CPU effectively overcomes the defects of the traditional way; and in addition, the invention enhances the utilization rate of the CPU, greatly reduces the hardware cost and can also effectively reduce the power consumption of an integral system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless router. Background technique [0002] At present, the design methods of 3G wireless routers all adopt the hardware architecture of two CPUs, the application processor (AP) and the communication processor (CP). The 3G communication is completed by the communication processor (CP), and the application software of the wireless router adopts the application processor ( AP) completed. The CPU utilization is very low, and the hardware cost is very high. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and aims to provide a single-CPU 3G wireless router which improves CPU utilization. [0004] The present invention is achieved through the following technical solutions: a 3G wireless router with a single CPU, including a WIFI antenna (WIFI-RF), a 3G antenna switch (3G-RF), a power management unit (PMU), a WIFI module and a co...
