 Abstract: A number of scientific applications start their life as a Matlab prototype that is later re-implemented in a low level programming language, typically C++ or Fortran for the sake of performance. Bohrium is a project that seeks to eliminate both the cost and the potential errors introduced in that process. Our goal is to support all execution platforms, and in this work we introduce the Bohrium Processing Unit, BPU, which will be the FPGA backend for Bohrium. The BPU is modeled as a PyCSP application, and the clear advantages of using CSP for simulating a new CPU is described. The current PyCSP simulator is able to simulate 2^20 Monte Carlo simulations in less than 35 seconds in the smallest BPU simulation.
