Abstract:
1. A data outputting method for interpolating and outputting data based on an input address comprising: a step of, when an address is input, generating a first memory address which is made up of a specified address high-order bit portion of the input address, and obtained by excepting a specified address low-order bit portion from the input address; a step of reading from a data storing unit a first compressed data stored at the first memory address and a second compressed data stored at a second memory address associated with the first memory address, and the first compressed data and the second compressed data which each are compressed by excepting a specified low-order bit part from respective original data; a step of expanding the first compressed data and the second compressed data, based on the specified address low-order bit portion of the input address, the read first compressed data; and the read second compressed data, to obtain a first expanded data and a second expanded data; a step of performing interpolation between the first expanded data and the second expanded data to obtain at least one expanded interpolation data; and a step of outputting the at least one expanded interpolation data, and at least one of the first expanded data and the second expanded data.
