Short Content: The data switchboard's transfer rate is very high, when its and serial port correspondence, divides into before the transmission the data two parts to transmit separately the serial port, then after data merging switch each serial port data merging in together and transforms the PCM class. This article introduced based on CPLD the chip EPM7128 design data merging switch. 1 data merging switch hardware circuit EPM7128 is the programmable large-scale logical component, is ALTERA Corporation's MAX7000 serial products, has ...

Short Content: Abstract: Introduced one kind based on the complex programmable logical component (CPLD) 120MHz high speed A/D gathering card design method. Has given this kind of gathering card hardware schematic circuit and the main software design mentality. Uses this design method design the data acquisition clamping apparatus to have including negative delay trigger and so on many kinds of triggering ways, has the volume to be small, operation reliable, control simple and so on characteristics.Key word: High speed A/D; CPLD; Negative ...

Short Content: Abstract: The small scale LED lattice demonstration use is widespread, uses when the monolithic integrated circuit controls, needs to expand the massive peripheral resource, and is not advantageous carries on the expansion, the revision and the maintenance. Has in the system programmable logic component is rich the I/O mouth and the internal resources, component's programming and the revision also great convenience. In this article, uses in system programmable logic component EPM7128 realizes as the core to the LED lattice demonstration ...
