Abstract: A medium for culturing Antrodia cinnamomea includes a carbon source, a nitrogen source, vitamin A, agar and a solvent. The medium includes 8-16 grams/liter of the carbon source, 0.4-1.6 grams/liter of the nitrogen source and 4 grams/liter of vitamin A. Moreover, a method for culturing Antrodia cinnamomea includes inoculating the medium with mycelia of Antrodia cinnamomea. The mycelia of Antrodia cinnamomea inoculated on the medium is cultured at 20-27° C. for 28-50 days.

Abstract: The invention discloses a data transfer protection apparatus for a flash memory controller, placed between Bose-Chaudhuri-Hocquenghem (BCH) and NAND Flash Chip. In encode path the hardware module selects a sequence of constant values, exclusive-or the original parity with that constant value. In decode path the hardware module detects the parity period, exclusive-or the parity which is read out from NAND Flash Chip with the same constant value sequence.

Abstract: A method for improving variable length decoding performance is provided. A variable length decoding module decodes a coded data to obtain a decoded data and a subsequent module receives the decoded data to perform further processing. A buffering module is coupled between the variable length decoding module and the subsequent module, and buffers the decoded data decoded by the variable length decoding module. A read part of the buffering module is cleared so that a content of an unused area of the buffering module is a predetermined value when the subsequent module reads the decoded data from the buffering module, wherein the unused area is a part of the buffering module except for the unread decoded data. The variable length decoding module does not write zero values of the decoded data into the buffering module when the variable length decoding module reads a zero output instruction among the coded data.
