  • Mono-dimensional reverse cosine transform computing device
    Patent number: 4912668
    Abstract: A device for computing 16 mono-dimensional direct cosine transforms from 16 luminance values having an input memory. A first computing device delivers respectively two values of the form A+B and (A-B).times.D, where A and B are two values applied respectively to two inputs of the first computing device and where D is a predetermined coefficient. A first intermediate value storage device uses the first computing device for 32 similar operations. A second computing device delivers a value of the form E+G, where E and G are two values applied consecutively to the input of the second computing device. A second intermediate value storage device reuses the second computing device for 17 additional operations. Finally, a device changes the order of the transformed values.
