I-Hsuan Lee has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10917662
    Abstract: An encoding method is used for encoding an image. The image includes a plurality of blocks each having a plurality of pixels. The encoding method includes: encoding a plurality of data partitions of block data of a block in the image to generate a plurality of compressed bitstream segments, respectively; and combining the compressed bitstream segments to generate an output bitstream of the block. A bit group based interleaving process is involved in generating the output bitstream. According to the bit group based interleaving process, each of the compressed bitstream segments is divided into a plurality of bit groups each having at least one bit, and the output bitstream includes consecutive bit groups belonging to different compressed bitstream segments, respectively.

  • Patent number: 10564706
    Abstract: A power source analysis method includes receiving a target number, performing voltage drop analysis on a plurality of power sources in a power delivery network (PDN) to determine respective supply currents of the power sources, sorting the supply currents of the power sources, and selecting a plurality of target power sources from the power sources according to a sorted result. The total number of the selected target power sources equals the target number.

  • Patent number: 10339253
    Abstract: A method of yield prejudgment and bump re-assignment for a die is provided. The die includes a plurality of areas. Each area is electrically connected to a substrate through a corresponding bump. The successful-connection probability of each area is prejudged. The die is divided into a signal region and a short-circuit region according to the successful-connection probabilities. The positions of the bumps are arranged so that signal bumps are disposed in the signal region and power bumps are disposed in the short region.
