Abstract

An information processing apparatus includes a first circuit configuration section, a second circuit configuration section and a circuit configuration controller. The first circuit configuration section includes a first circuit configuration configured by a plurality of first calculation units. Each of the first calculation units has a circuit being configured to be dynamically reconfigured. The second circuit configuration section includes a second circuit configuration configured by a plurality of second calculation units. Each of the second calculation units has a fixed circuit. The circuit configuration controller controls the first circuit configuration and the second circuit configuration in accordance with processing time to be taken for performing information processing.

Claims

1. An information processing apparatus comprising:

a first circuit configuration section that includes a first circuit configuration configured by a plurality of first calculation units, each of the first calculation units having a circuit being configured to be dynamically reconfigured;

a second circuit configuration section that includes a second circuit configuration configured by a plurality of second calculation units, each of the second calculation units having a fixed circuit; and

a circuit configuration controller that controls the first circuit configuration and the second circuit configuration in accordance with processing time to be taken for performing information processing.

2. The information processing apparatus according to claim 1, wherein the first calculation units have a larger grain size than the second calculation units.

3. The information processing apparatus according to claim 1, wherein the first circuit configuration is changed in a shorter time than the second circuit configuration.

4. The information processing apparatus according to claim 1, wherein

each of the first calculation units is configured by a plurality of calculation circuits, and

each of the second calculation units is configured by a single calculation circuit.

5. The information processing apparatus according to claim 1, wherein the circuit configuration controller controls the first circuit configuration when performing information processing that does not use a processing result of first information for performing processing of second information.

6. The information processing apparatus according to claim 1, wherein the circuit configuration controller controls the second circuit configuration when performing information processing that uses a processing result of first information for performing processing of second information.

7. The information processing apparatus according to claim 1, wherein the circuit configuration controller controls the first circuit configuration using a part of the first calculation units of the first circuit configuration section.

8. The information processing apparatus according to claim 1, wherein the circuit configuration controller controls the second circuit configuration using a part of the second calculation units of the second circuit configuration section.

9. The information processing apparatus according to claim 1, wherein

the circuit configuration controller divides the second circuit configuration section into a plurality of areas, and

the circuit configuration controller controls the second circuit configuration to change circuit configuration of a target area included in the areas while the target area is not performing the information processing.

10. A method for controlling information processing apparatus, wherein the information processing apparatus includes

a first circuit configuration section that includes a first circuit configuration configured by a plurality of first calculation units, each of the first calculation units having a circuit being configured to be dynamically reconfigured, and

a second circuit configuration section that includes a second circuit configuration configured by a plurality of second calculation units, each of the second calculation units having a fixed circuit, and

the method comprises controlling the first circuit configuration and the second circuit configuration in accordance with processing time to be taken for performing information processing.

11. A computer readable medium storing a program causing a computer to execute a process for controlling an information processing apparatus,

wherein the information processing apparatus includes
