A reconfiguration circuit of an integrated circuit and a method thereof

Abstract

The invention relates to the field of integrated circuits, and discloses a reconfiguration circuit of an integrated circuit and a method thereof. System enters user mode, the user logic module outputsa reconfiguration signal according to the reconfiguration requirement; the reconfiguration selection logic module outputs a reconfiguration control signal according to the reconfiguration signal; themulti-channel configuration code stream configuration register module outputs the information of the reconfiguration code stream according to the reconfiguration signal; the flash memory reading control logic module reads the reconfiguration data from the flash memory according to the reconfiguration control signal and the information of the reconfiguration code stream, and the configuration logic module configures the reconfiguration data into the integrated circuit to realize the reconfiguration of the integrated circuit. According to the circuit and the method, when the integrated circuitworks normally, a new configuration code stream can be automatically selected according to system requirements to reconfigure the integrated circuit so as to realize new functions, and the flexibilityand multifunctionality of system design are greatly improved.

Description

technical field [0001] The present application relates to the field of integrated circuits, in particular to an integrated circuit reconfiguration circuit and its method. Background technique [0002] As the system becomes more and more complex, designers require to do more with as little cost as possible. Take FPGA as an example. Although FPGA has a lot of flexibility, it is increasingly demanding on cost, board space and power consumption. Constraints call for more efficient design strategies. However, in current FPGA systems, only one configuration code stream is often saved in the configuration memory, or the function of updating the original configuration code stream is provided in a more advanced system, but the new function needs to be re-downloaded through an external trigger, which not only increases the The design cost of the system also affects the stability of the system. [0003] If the FPGA can intelligently choose to load a certain configuration file to achi...
