Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] The present invention relates generally to wireless communication. More specifically, a configurable wireless interface is disclosed. BACKGROUND OF THE INVENTION [0002] With the increasing popularity of portable computing devices and wireless connectivity, there has been a proliferation of wireless communication standards and protocols. For example, a Personal Digital Assistant (PDA) may communicate with several other portable or non portable devices wirelessly and run wireless applications. Such a PDA may at different times (and in some cases, concurrently) implement WLAN, Bluetooth.TM., GPS, Cellular, Cordless or other RF applications. Currently, each such application requires its own software and hardware and as a result each application that is enabled contributes individually to the cost of the portable device. In addition, each application is generally configured in the device before the device is sold, or in some cases purchased as a hardware add on. [0003] It would be very useful if a device could be developed that could be configured and reconfigured to implement different wireless applications and protocols as desired. Furthermore, if such a device could use common hardware or reconfigurable software resources to implement different protocols or applications, then the cost of potentially including a large selection of applications in a device could be reduced. What is needed, therefore, is a configurable wireless interface that could be included in a device to allow that device to be configured to run multiple wireless applications. SUMMARY OF THE INVENTION [0004] It should be appreciated that the present invention can be implemented in numerous ways, including as a process, an apparatus, a system, a device, a method, or a computer readable medium such as a computer readable storage medium or a computer network wherein program instructions are sent over optical or electronic communication links. Several inventive embodiments of the present invention are described below. [0005] A configurable wireless interface is disclosed. In one embodiment, a multistandard RF receiver includes a plurality of selectable mixers; a plurality of selectable amplifiers; a configurable analog filter; and a configurable analog to digital converter. [0006] In one embodiment, a multistandard RF transmitter includes a plurality of selectable mixers; a plurality of selectable amplifiers; a configurable analog filter; and a configurable analog to digital converter. [0007] In one embodiment, a multistandard RF receiver includes a data interface for sending data to a host controller and a control interface for receiving configuration commands from the host controller. The configuration commands identify a wireless standard that is to be implemented by the RF receiver. An RF processor processes an RF signal wherein the processed RF signal is output to the host controller on the data interface. [0008] In one embodiment, a multistandard RF transmitter includes a data interface for receiving data from a host controller and a control interface for receiving configuration commands from the host controller. The configuration commands identify a wireless standard that is to be implemented by the RF transmitter. An RF processor processes an RF signal. The processed RF signal is transmitted in accordance with the wireless standard. [0009] These and other features and advantages of the present invention will be presented in more detail in the following detailed description and the accompanying figures which illustrate by way of example the principles of the invention. BRIEF DESCRIPTION OF THE DRAWINGS [0010] The present invention will be readily understood by the following detailed description in conjunction with the accompanying drawings, wherein like reference numerals designate like structural elements, and in which: [0011] FIG. 1 is a block diagram illustrating how a modular RF interface interacts with a host. [0012] FIG. 2A is a diagram illustrating an architecture used in one embodiment of a modular wireless interface that includes an RF/IF system with both a transmitter and a receiver. [0013] FIG. 2B is a diagram illustrating in detail a configurable signal path between the amplifiers, mixers, and digital filter shown in FIG. 2A on the receive side. [0014] FIG. 2C is a diagram illustrating in detail a configurable signal path between the amplifiers, mixers, and digital filter shown in FIG. 2A on the transmit side. [0015] FIG. 3 is a diagram illustrating a feature register included in the modular RF interface. [0016] FIG. 4A is a diagram illustrating an application table for the transmit side included in a control database as shown in FIG. 1. [0017] FIG. 4B is a diagram illustrating an application table for the transmit side included in a control database as shown in FIG. 1. [0018] FIG. 5 is a flow chart illustrating a process for programming the modular RF interface to include a new application by adding a new application table. [0019] FIG. 6 is a flow chart illustrating a process for configuring the modular RF interface to implement a selected application. [0020] FIG. 7 is a flow chart illustrating a process for the modular RF interface reporting to a host the features that are available. Continue reading about Configurable wireless interface...
