Information processing apparatus and method, and program

Disclosed herein is an information processing apparatus, including: setting means for setting, a maximum transfer size; calculation means for subtracting a second data amount from a first data amount to calculate a third data amount; boundary determination means for determining whether this transfer will involve a page boundary being extended across; buffer boundary determination means for determining whether this transfer will involve a buffer size being exceeded; transfer size determination means for determining whether or not the third data amount is equal to or less than the maximum transfer size; and determination means for determining a data amount of data to be transferred within limits of the third data amount, based on a first determination made by the boundary determination means, a second determination made by the buffer boundary determination means, and a third determination made by the transfer size determination means.
