Abstract
An extensible configurable FPGA storage structure and an FPGA device, where the FPGA storage structure includes: a plurality of local storage units, a controller and two clock buffers, where the two clock buffers are separately used for providing different clock signals for two clock input ports of the controller; the controller is used for receiving a write address signal input externally, and driven by the clock signals, generating a plurality of enable signals and write address decoding signals to be output to the plurality of local storage units; and each of the local storage units includes a local memory and a multiplexer used for providing input data for the local memory; and, based on a configuration mode of each local storage unit, generates output data in the corresponding configuration mode according to the enable signals, input write address decoding signals or read address signals, and the input data.
