This large on-chip dual-ported memory enables sustained processor and I/ O performance, without the need for external memory. 大容量片内双端口存储器设计可为处理器和I/O带来持续的性能,无需添加外部存储器。
A Dual-ported Variable-way L1 D-cache for DSP 用于DSP的双端口、多路可变L1D-cache设计
The two CPUs of single chip realized the data exchange through the dual-ported RAM CY7C133; and the latch was used as virtual bus to realize the data bus expansion. 单片机2个CPU间通过双口RAMCY7C133完成数据交换,利用锁存器作为虚拟总线实现数据总线的扩展。
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. 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 author designed the logic circuit to control the synchronous& asynchronous signal switch and other logics used by FPGA, realized the data exchange between the host computer and Smart-Communication Board used by the Dual-Ported RAM, and finally designed a high-speed Smart-Communication Board. 设计中用FPGA来实现同异步的转换以及逻辑控制电路,并用双口RAM来实现上位机与智能通信板的数据交换,设计出一种高速的智能通信板。
