Patent ID: 8666166

Claim:
A system comprising: column transform circuitry configured to perform a column transform on first data to generate second data; row transform circuitry configured to perform a row transform on said second data to generate third data, and wherein said column transform circuitry is configured to separate a column of said first data into a first portion and a second portion, wherein said first portion of said column comprises a first plurality of values, and wherein said second portion of said column comprises a second plurality of values, wherein said column transform circuitry is configured to determine whether said first plurality of values of said first portion of said column comprises at least one zero value, wherein said column transform circuitry is further configured to determine whether said second plurality of values of said second portion of said column comprises at least one zero value, wherein said column transform circuitry is further configured to process said first portion and said second portion contemporaneously, and wherein said column transform circuitry is further configured to perform, when performing said column transform, an operation associated with at least one data value comprising a zero value, wherein said at least one data value is selected from a group consisting of at least one data value of said first portion of said column and at least one data value of said second portion of said column.
