PCI Express (PCIe) Data Streaming
eXpert FPGA DSP Feature for CompuScope PCIe Digitizers

All Gage PCI Express (PCIe) CompuScope Digitizers are capable of streaming acquired waveform data through the PCIe bus directly to the host PC RAM by utilizing the eXpert PCIe Data Streaming Firmware.

By contrast, in standard Memory Mode operations the waveform data is first acquired to the digitizer card's onboard memory, acquisition is stopped, and then the data residing in onboard memory can be transferred to the host PC system.

eXpert PCIe Data Streaming Mode operations provide two distinct advantages over standard Memory Mode. First, Streaming Mode may overcome the acquisition time limit imposed by the size volume of the dedicated onboard digitizer memory. Second, in Streaming Mode the user does not need to await completion of waveform acquisition before accessing the resulting waveform data, which is necessary in Memory Mode.

Thus Streaming Mode allows for the capability to simultaneously acquire and stream data to targeted host CPUs or GPUs for further signal processing analysis and/or to high-speed storage systems for signal recording operations.
