摘要
SDRAM是一种具有同步接口的高速动态随机存储器,它与DSP相结合运用在指纹图像处理中,提高了指纹图像处理的速度.但SDRAM与DSP的输出信号不同,故需加以接口电路.本文利用现场可编程门阵列(FPGA),设计实现TMS320C5402与SDRAM接口电路,使SDRAM在指纹处理模块中充分发挥了数据缓存的作用.
The application of SDRAM in fingerprint recognition system is stated.The SDRAM has become the chief choice of the buffer storage because of the high speed,big capacity,but it cannot directly interface with DSP. Therefore,FPGA is adopted to implement the interface between DSP and SDRAM.
