Linköping, Sweden, April 4, 2018 – Teledyne SP Devices today announced the release of peer-to-peer data transfer firmware and software.
With this solution data can be transferred from a digitizer to a peripheral device at astonishing peak rates of up to 6.8 GBytes/s.
Many modern data acquisition systems produce vast amounts of data which needs to be processed.
The data rates are often extremely high and therefore application-specific processing requires high-performance processing units such as field-programmable gate arrays (FPGAs) or graphics processing units (GPUs).
Both methods have advantages but the latter offers cost-efficient processing capabilities and is programmed in CUDA™ or OpenCL™ supporting parallel computing platforms.
In addition to the already offered open FPGA architecture Teledyne SP Devices is now extending product functionality and flexibility even further by also introducing peer-to-peer streaming support.
This streaming allows for reliable high-speed data transfers from selected digitizer models to a number of GPUs from AMD and NVIDIA.
Streaming is supported both for Windows and Linux and is based on PCIe x8 Gen3 which allows for peak transfer rates of up to 6.8 Gbytes/s.
With peer-to-peer technology the data is transferred directly from the digitizer to the GPU which means that no load is added to the CPU of the host PC.
This is a huge advantage compared to conventional solutions which require data to be copied via the host PC and therefore add significant burden on both CPU and RAM of the computer.
With peer-to-peer the CPU can instead be used for other tasks.
Jan-Erik Eklund, Digitizer Product Manager at Teledyne SP Devices, commented, “Our peer-to-peer solution offers significant performance advantages compared to alternative solutions and it adds exciting new possibilities for our customers.”
