Abstract
To reduce overhead of data transfer between processor cores and improve a processing capability of a processor, there is provided a processor including: a CPU for performing computing processing; an internal memory for storing data; and a data transfer unit for performing data transfer between the internal memory and a shared memory, in which: the data transfer unit includes: a command chain module for executing a command sequence formed of a plurality of commands including a data transfer instruction; and a monitor module for reading data set in advance in the internal memory and repeatedly monitoring the data until a comparative value and a value of the data become equal to each other, when one of the plurality of commands of the command sequence thus read is a predetermined command; and the command chain module executes a next command in the command sequence after the monitor module has finished monitoring.
