Abstract:
1. An inverse discrete cosine transform apparatus comprising: an inverse discrete cosine transform core for receiving incoming data in the frequency domain and transforming the data to spatial domain, the inverse discrete cosine transform core being configured to convert an incoming M×N data block into an N′×N′ data block, process the N′×N′ data block to produce an N′×N′ output block, and derive and M×N result from N′×N′ output block; and a memory device associated with the inverse discrete cosine transform core for storing transform coefficients for transforming the pixel data according to an associated coding standard, wherein the appropriate transform coefficients are loaded into the memory device according to the coding standard of the incoming data, and an inverse discrete cosine transform operation is performed by the transform core according to the stored transform coefficients.
