摘要： Power consumption can be suppressed while maintaining an appropriate execution speed. The information processor (1) has an interpreter for interpreting a source program or intermediate language program and a run-time translator for translating the program into a machine language program native to the computer. The information processor (1) comprises a power-saving request monitor (126) for monitoring whether or not there is a power-saving request from an input interface or a predetermined power-saving request in a given memory, and a power-saving translation controller (129). The power-saving request makes a request for suppression of the power consumed by the processor (1). The power-saving translation controller (129) makes a decision as to whether the run-time translator executes run-time translation of the program according to whether there is the power-saving request. Based on the result of the decision, the translation controller instructs the run-time translator to execute the run-time translation.

摘要： A coprocessor executing one among a set of candidate kernel loops within an application operates at the minimal clock frequency satisfying schedule constraints imposed by the compiler and data bandwidth constraints. The optimal clock frequency is statically determined by the compiler and enforced at runtime by software-controlled clock circuitry. Power dissipation savings and optimal resource usage are therefore achieved by the adaptation at runtime of the coprocessor clock rate for each of the various kernel loop implementations.

摘要： When parallel processing is performed by a system configured by a plurality of processors and a multicore processor chip, power control code can be reduced by dynamically changing the number of processors for performing the parallel processing and an operation clock of each processor. A translation device includes: a parallel loop processing detection unit configured to detect from the source code a loop processing code for execution of an internal processing operation for a given number of repeating times, and an independent parallel loop processing code in the internal processing operation performed for each repetition to be concurrently processed; and a dynamic parallel conversion unit configured to generate a control core code for control of the number of repeating times in the parallel loop processing code and a parallel processing code for changing the number of repeating times corresponding to the control from the control core code. The technology also relates to a translating method, a translating program, a control method for a processor core, and a processor.

摘要： Methods, apparatus and software products are described for design-time data-assignment techniques for hierarchical memories, e.g., multi-banked memories in an essentially digital system as well as methods, apparatus and software products for run-time memory management techniques of such a system. Memory assignment techniques are described for assigning data to a hierarchical memory particularly for multi-tasked applications where data of dynamically created/deleted tasks is allocated at run-time. The energy consumption of hierarchical memories such as multi-banked memories depends largely on how data is assigned to the memory banks. Methods, apparatus and software products are described for design-time data-assignment techniques for hierarchical memories, e.g., multi-banked memories in an essentially digital system which improve a cost function such as energy consumption.
