摘要:
The present invention provides a method for converting application code into optimised application code or into execution code suitable for execution on a computation engine with an architecture comprising at least a first and a second level of data memory units. The method comprises: obtaining application code, the application code including data transfer operations between said levels of memory units; and converting at least a part of the application code such that data transfer operations between and data layout within said memory units are modified. The modification may include an improvement with respect to energy and/or performance. The converting step comprises: (a) scheduling of data transfer operations from a first level of memory units to a second level of memory units such that accesses of data accessed multiple times are brought closer together in time than would be the case in the original code, and thereafter, (b) deciding on layout of the data in the second level of memory units to improve the data layout locality such that data which is accessed closer together in time is also brought closer together in the layout than would be the case in the original code,
whereby step (a) does not decide on the internal organization of at least some of the data transferred, hence fixing the scheduling of data transfer operations only partially while also partially, but not yet fully, fixing the placement of all the data transferred, thereby providing freedom to subsequent step (b).

Method and apparatus of fabricating a core laminate Printed Circuit Board structure with highly planar external surfaces is provided. A pre-formed flat material including a first resinous sub-material and a second carrier sub-material is used to planarize external surfaces. During lamination, uniform pressure is applied to the pre-formed flat sheet which covers the upper surface of the printed circuit. The resinous material of the first sub-material flows to fill the crevices, vias, etc. of the upper surface of the PCB. Moreover, due to the uniform pressure on the pre-formed flat sheet, the resinous first sub-material is planarized. This planarized surface provides a suitable base substrate for a thin film multilayer build-up structure and that provides electrical connections between the thin film top layers and the Printed Circuit Board - style core layers.

The present invention discloses a method for forming germanides on substrates with exposed germanium and exposed dielectric(s) topography, thereby allowing for variations in the germanide forming process. The method comprises the steps of depositing nickel on a substrate having topography, performing a first thermal step to convert substantially all deposited nickel in regions away from the topography into a germanide, selectively removing the unreacted nickel, and performing a second thermal step to lower the resistance of formed germanide.
