The present invention provides an image encoding device that can balance encoding at a high compression ratio and restoration of a high-quality image by decoding in a short processing time. Compression mode determination meansdetermines a compression mode to be one of DPCM and PCM based on target pixel data inputted from a terminaland predicted data calculated by a predetermined method. For the DPCM, DPCM compression meanscompresses a difference value between the target pixel data and the predicted data to DPCM encoded data having a predetermined DPCM code length. For the PCM, PCM compression meanscompresses the target pixel data to PCM encoded data having a PCM code length determined by PCM code length determination means. The PCM code length determination meanscalculates the PCM code length for each piece of target pixel data such that a total of post-encoding code lengths becomes an allowable value or less in a unit of predetermined pixel group among the plurality of pixels. Tag/code output meansoutputs the encoded data by adding a tag indicating whether the compression mode is the DPCM or the PCM to the encoded data.

A system for detecting power consumption of an integrated circuit obtains a frequency of data holding operations, unreferred data storing operations, and unupdated data storing operations with a data holding operation frequency calculating section, an unreferred data storing operation frequency calculating section, and an unupdated data storing operation frequency calculating section based on the number of times of a signal transition from connection information of the integrated circuit and control conditions when data is referred to registers, and obtains power consumption caused by each of the operations from the number of times of the signal transition, a load capacity, and an operation voltage. In this manner, the system distinguishes, in a function design phase, between signal transitions in the designed integrated circuit that are necessary to processing and those that are not definitely necessary, and detects reducible power consumption caused by the signal transitions that are not definitely necessary. Places where improvements can be made to reduce the power consumption of the circuit can be thus detected at an earlier phase in the design process.
