One of the key problems in hardware/software codesign is hardware/software partitioning. This paper describes a new approach to hardware/software partitioning using integer programming (IP). The advantage of using IP is that optimal results are calculated for a chosen objective function. The partitioning approachworks fully automatic and supports(More)
Two main aspects in hardware/software co-design are hardware/software partitioning and co-synthesis. Most co-design approaches work only on one of these problems. In this paper, an approach coupling hard-ware/software partitioning and co-synthesis will be presented, working fully-automatic. The techniques have been integrated in the co-design tool COOL1(More)
One of the key problems in hardware/software codesign is hardware/software partitioning. This paper describes a new approach to hardware/software partitioning using integer programming (IP). The advantage of using IP is that optimal results are calculated respective to the chosen objective function. The partitioning approach works fully automatic and(More)
The current decay in response to a sudden change of applied bias up to 1 V has been measured on a methylammonium lead triiodide perovskite solar cell with titania and spiro-OMeTAD transport layers, for temperatures between 258 and 308 K. These measurements are highly reproducible, in contrast to most other techniques used to investigate perovskite cells. A(More)
