Embodiment Construction

[0019] figure 1 A reconfigurable chip 20 is shown that can be used in one embodiment of the invention. The reconfigurable chip includes a foreground configuration plane 22 and a background configuration plane 24 . The foreground configuration plane 22 configures the elements of the reconfigurable structure 26 to enable a portion of the communication system design to be implemented. In a preferred embodiment, reconfigurable chip 20 also includes a processor 28, such as a reduced instruction set computing (RISC) central processing unit (CPU). In one embodiment, CPU 28 runs portions of the communication system algorithms that are difficult to implement in a reconfigurable configuration. In a preferred embodiment, reconfigurable fabric 26 includes a plurality of reconfigurable data path units, storage elements and interconnection units. In one embodiment, the datapath unit includes comparators, an arithmetic logic unit (ALU), and registers configurable to implement the operatio...

Abstract

A wireless communication system can be implemented by using one or more reconfigurable chips, the reconfigurable chips having background and foreground configuration planes. The background plane can be loaded with one communication algorithm, while another portion of the communication algorithm is configured into the foreground plane and operating in the reconfigurable fabric. The switching between the foreground and background configurations can be done almost instantaneously. The system of the present invention allows a complicated communication system, such as a base station receiver for a wireless communication system, to be implemented on a small reconfigurable chip rather than a much larger FPGA.

Description

Background of the invention [0001] The present invention relates to communication systems, and more particularly, the present invention relates to wireless communication systems. [0002] Wireless communication systems are typically implemented using integrated circuits. For many cases, application specific integrated chips (ASICs) are used to implement the communication system. This is especially true for wireless communication base stations that can be used to serve large numbers of users. The requirement for flexibility in communication systems has led to the use of Field Programmable Gate Arrays (FPGAs) to implement parts of the communication systems. However, FPGAs have a considerable down side. The size and thus cost of FPGAs used to implement complex algorithms used in wireless communication systems, especially base stations, can be significant. Therefore, a flexible and inexpensive solution for implementing a computer communication system is desired. Contents of ...
