ABSTRACT:
A vector processing device includes a vector unit having operation pipelines and a vector register connected to the operation pipelines, a memory unit to be operated by the operation pipelines and results of operations obtained from the operation pipelines, and a memory control unit having a data buffer provided between the vector register and the memory unit. The vector processing device also includes data buffer valid counter counting the number of pieces of data read from the vector register and sent to the data buffer, and pipeline stop predictor selectively interrupting outputting an access request from the vector unit to the memory unit on the basis of the number of pieces of data counted by the data buffer valid counter when the operation pipelines are chained via the vector register.
