我们在单片FPGA中完成了6个端口、32位数据总线宽度交叉开关的设计。
We complete the design of crossbar switch with 6 ports and 32 bits data bus on one chip of FPGA.
端口0也是复低位地址和在利用外部程序和数据存储器的数据总线。
Port 0 is also the multiplexed low-order address and data bus during access to external program and data memory.
双端口ram是一种特殊的数据存储芯片，利用双端口ram可以实现双高速单片机总线方式的数据共享。
The dual-ported RAM is a kind of special memory, and the bus data share between double high-speed microprocessors is carried out by using it.
数据采集卡采用PC I局部总线接口，通过双端口ram进行数据传输。
