PCI Data Acquisition Card receives high speed data in a serial form and
transfers to storage media or other like devices through 64-bit 66MHZ
PCI PC interface. The card supports two serial channels each up to 105
MHz serial data rate. Very useful for real-time high speed data
transfer from external devices or data collection equipments and store
into HDDs attached to PCs.
The glue logic designed in the FPGA reads the serial data from both the
inputs using the serial clock and converts the serial data into 64-bit
parallel words. A frame sync sequence is detected to determine the
start of the input serial data frame. The converted parallel data is
buffered on the onboard FIFOs. The size of the FIFO depends on the
serial data rate and the latency of the data transfer to the PC. Using
DMA transfer the FIFO contents are transferred to the PC RAM. The
special software application transfers the data from PC RAM to the PC
hard disk. The design ensures no loss of data in the process of
transfer from the serial inputs to the storage device.
