[Lightning talk] Next generation computing with fpga
- 2. FPGA ? A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence "field-programmable” Source: Wikipedia Simplified: You can create your own processor Why should one care ?

We are now, taking those; neural nets, deep neural nets, convolution nets and asking ourselves; What if we can run them not just on cpu’s or gpu’s, what if we can run them on silicon ?” Satya Nadella Source: Innovation Keynote Ignite 2016

- 19. Specifying/Programming Direct – VHDL – Verilog – Gate Diagrams Indirect: – (HLS) C – Open-CL VHDL of Blinking light (“Hello World”)
- 21. Synthesis,Mapping,Placing,Routing Automatic, Manual, or Both Specify Can take weeks if very complex
- 24. Conclusion FPGA’s is a very interesting technology – Powerful – Efficient FPGA’s is also a difficult technology – Steep learning curve – Synthesis, mapping, and routing can take ages – Highly parallel and physical interference makes for fun debugging sessions – Physical behavior (Heating of chip, chirp) Use abstractions like open-cl if you're able to Title document 2407-11-16
