Samsung also uses a coarse-grained reconfigurable array for some operations. My understanding is that looks similar to, or is a derivative of, the ADRES research project.
There are lots of interesting looking papers to be presented at ISFPGA this year, including a Wednesday afternoon workshop on using FPGAs in the datacenter. The conference website is given above, but here is a direct link to the advance program: http://www.eecg.utoronto.ca/FPGA2014/fpga_2014_program.pdf
@Sanjib.A: Are there any smart phones that uses FPGAs?
Indeed yes. My understanding is that -- of the top 5 smartphone providers -- FPGAs are shipping in the majority. In fact, there are a few teardowns out there on the Web that show Lattice FPGAs (in the form of their SiliconBlue devices) are in the Samsung Galaxy S4.
Are there any smart phones that uses FPGAs? Lattice started late for coming out with FPGAs to the market compared to Xilinx and Altera, they maintained pace by coming out with innovative products like MachXO, programmable analog and iCE40 series of FPGAs. The iCE40 is an innovative product for the high volume consumer market. I will miss the event but would keep on watching this space for more news from the people attending the conference.
