A hardware design capable of supporting high‐efficiency video coding (HEVC) inverse transform (IDCT) is developed for a 32‐point transform unit using a single one‐dimensional (1D) transform core with two transposed memories to reduce area overhead. The proposed 1D core employs two calculation paths to obtain high throughput and is able to calculate first‐dimensional (1st‐D) and second‐dimensional (2nd‐D) transformations simultaneously along two parallel paths. The results from a practical implementation of the chip demonstrate that the proposed design presents the smallest circuit area among existing 2D transform cores.
