Abstract

A processing device and a method of processing data between a plurality of modules in the processing device. The method includes monitoring packets exchanged between a transmission module and a reception module from among the plurality of modules; determining whether a task being executed by the processing device has switched based on the monitored packets; when the task being executed by the processing device has switched, obtaining a packet layout encoded by taking into account transitions to occur due to processing of data packets regarding the switched task; and executing the switched task by using data packets to which the obtained packet layout is applied.

Claims

1. A method of processing data between a plurality of modules in a processing device, the method comprising:

monitoring packets exchanged between a transmission module and a reception module from among the plurality of modules;

determining, based on the monitored packets, whether a task being executed by the processing device has switched;

when the task being executed by the processing device has switched, obtaining a packet layout that is encoded based on determining transitions of data bits to occur due to processing of data packets by the switched task; and

executing the switched task utilizing data packets to which the obtained packet layout is applied.

2. The method of claim 1, wherein the transmission module and the reception module exchange packets via a network-on-chip system.

3. The method of claim of claim 2, wherein the determining whether the task being executed has switched is based on an increase in monitored packets being processed by the transmission module or the reception module, or by a change in characteristics of data bits included in the monitored packets.

4. The method of claim 1, wherein the processing device determines at least one of whether the task being executed has switched from a first application to a second application and whether the task being executed has switched from a first task to a second task of the same application.

5. The method of claim 1, wherein the obtaining of the packet layout includes selecting a packet layout corresponding to the switched task from among a plurality of packet layouts defined in advance.

6. The method of claim 5, wherein the plurality of packet layouts are defined in advance by determining transitions of bits to occur due to processing of data packets regarding respective tasks executable by the processing device.

7. The method of claim 1, wherein the obtaining of the packet layout is determined to minimize transitions between data bits having the same position in different packets, to which the obtained packet layout is applied, during execution of the switched task.

8. The method of claim 1, further comprising:

executing a first task for a preset period of time;

collecting packets processed by the plurality of modules during the execution of the first task;

counting a number of times that a value of data bits is 1 at respective positions of the data bits in the collected packets;
