Method and device for reducing power consumption in application specific instruction set processors

摘要

The present invention provides a compile or pre-compile method and a device for converting first program code into second program code, such that the second program code has an improved execution on a targeted programmable platform. The method according to embodiments of the present invention comprises
grouping operations on data for joint execution on a functional unit of the targeted platform, scheduling operations on data in time, and
assigning operations to an appropriate functional unit of the targeted platform,
wherein detailed word length information is used in at least one of the grouping, scheduling or assigning operations, rather than the typically used approximations like powers of two.
