Xilinx and Altera both took the next step in integrating System on Chips (SoC) with Field Programmable Gate Arrays (FPGA): put them both on the same die and connect them with a high speed interface. This talk will describe the Altera Socfpga platform, its current support in the mainline Linux kernel, lessons learned in using the vendor supplied information and what this new kind of dual core CPU and FPGA alliance opens up for possibilities in low latency RT applications.
