NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the Giano system simulator. eMIPS is a platform developed at Microsoft Research for researching reconfigurable computing. eMIPS allows dynamic loading and scheduling of application-specific circuits for the purpose of accelerating computations based on the current workload. NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research by Alessandro Forin and Neil Pittman. Microsoft Corporation has donated full copyright to The NetBSD Foundation. Platform support for eMIPS is the first part of Microsoft's contribution. The second part includes the hardware accelerator framework and will be proposed on tech-kern soon.
