引言大部分FPGA采用基于SRAM(静态随机存储器)的查找表逻辑形成结构,就是用SRAM构成逻辑函数发生器。SRAM工艺的芯片在掉电后信息就会丢失,需要外加一片专用配置芯片。在上电时,由这个专用配置芯片把数据加载到FPGA中,然后FPGA就可以正常工作。这就是在线可重配置ICR(In-Circui
Introduction Most FPGAs use SRAM (Static Random Access Memory) based look-up table logic to form a structure that uses SRAM to form a logic function generator. The chip of SRAM craft will be lost after losing the electricity, need to add one piece to dispose the chip specially. At power-up, data is loaded into the FPGA by this dedicated configuration chip, and the FPGA can then function properly. This is the online reconfigurable ICR (In-Circui
