Data storage solutions: in the internal FPGA achieve double-port RAM (FIFO) for the collection and storage of data, and complete Ethernet and TCP/IP protocols package synchronistically.
The signal processing efficiency is improved by using the EPLD and double-port RAM, and the data processing method that improves the mea s uring accuracy is designed.
The circuit design of the CAN communication module based on SJA1000 CAN controller and double-port RAM IDT7007 is completed,and the circuit design of data processing instrument based on SJA1000 CAN controller and 20-bit multi-range A/D converter is done,and the circuit design of output control instrument based on SJA1000 CAN controller and TLC5616 D/A converter is completed.
PMAC communicates with IPC based on double-port RAM, response time is little, fast and high-veracity, so it is a in common use communication mode has strong function .
This paper proposes a designing method for high-speed data acqusition system using double-port RAM. Since the data transmission time is no longer needed, a much higher data acqusition rate can be obtained by making full use of the fuctions of high-speed devices in the system. Moreover, the hardware truture is very simple and reliable.
The missile borne infrared image processor is a complex real-time infrared image signal processing system,It is abvious that a single CPU is not able to be employed to take such a great amount of computation tasks because of the stfict real-time requirement of the signal processor several multi-CPUcommu-nicatio n principles and methods has been discribed and a nalysed in this paper,and it is put forward that a multi-CPU parallel communication model with a double-port RAM as the common-shar...
In order to overcome data transportations speed limitation of computer, this paper proposes a design method of wide-band arbitrary waveform generator based on double-port RAM.system construction of the generator is discussed. Experiment result shows that the design method is right and worthy of hems applied.
