MLE presents first OS metrics for DTO-based DPR based on exemplary implementations of programmable accelerators for the Linux Kernel Crypto-API, implemented on the Xilinx Zynq 7000 platform at the FPGA4GPC (International Conference on FPGA Reconfiguration for General-Purpose Computing 2017) on 2017-05-09 & 2017-05-10. These metrics can guide future research on OSs forGPC on FPGAs. FPGA4GPC focusses on novel work in the field of reconfigurable systems optimized for the use in a general-purpose environment.
