INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

摘要

A storage section (101) configured to store data, a DMA section (106) configured to read video data from the storage section (101) by specifying an address and write them into the storage section (101), an address conversion rule storage section (104) configured to store an address conversion rule for converting the address specified by the DMA section (106), and an address conversion section (105) configured to convert the address specified by the DMA section (106) in accordance with the address conversion rule; the address conversion rule is a rule for converting addresses of a series of areas to addresses of the video data stored in a plurality of areas in the storage section (101); the address conversion section (105) includes an address conversion done-or-not determination section; and the address conversion done-or-not determination section determines, by comparing the address with a third area assigned to address conversion, whether the address conversion is done or not done.

1. An information processing device comprising:
a storage section configured to store video data; a DMA section configured to read video data from the storage section by specifying an address and write the read video data into the storage section or another storage section different from the storage section; an address conversion rule storage section configured to store an address conversion rule for converting the address specified by the DMA section; and an address conversion section configured to convert the address specified by the DMA section in accordance with the address conversion rule; wherein the address conversion rule is a rule for converting addresses of a series of areas to addresses of the video data stored in a plurality of areas in the storage section; the address conversion section includes an address conversion done-or-not determination section; and the address conversion done-or-not determination section determines, by comparing the address specified by the DMA section with addresses of a third area assigned to address conversion, whether the address conversion is done or not done.
