摘要:
A quantized coefficient coding apparatus used in a media coding system includes a determination module, a coding mode arbitration module and a coding module. The determination module determines whether a set of quantized coefficients are defined in a predetermined variable length coding (VLC) table to generate a determination result. When the determination result of the determination module is negative, the coding mode arbitration module determines a best coding mode corresponding to the set of quantized coefficients from a plurality of predetermined coding modes. The coding mode encodes the set of quantized coefficients according to the best coding mode.

The conventional apparatus for reading/writing storage devices need a built-in microprocessor control unit (MCU) to process commands. Thus, the flexiability (e.g.: supporting capacity of storage device) and the cost of the apparatus are not satisfied. The present invention employs a driver and a hardwire circuit to replace the MCU for money saving without changing other units in the apparatus. Moreover, the apparatus of the present invention can raise the supporting capacity of storage device and compatibility by just updating the driver.

A decoder for decoding a message using an arbitrary-side growing (ASG) Huffman tree including a plurality of codewords and symbols includes a database, a processing module, and a bit pattern matching module. The database stores a plurality of parameters corresponding to the ASG Huffman tree divided into several sub-trees according to a Hashemian cut operation and a bits-pattern-Xor (BPX) operation. The plurality of parameters include a bit pattern of a sub-tree of the ASG Huffman tree divided according to the BPX operation and a code length of the bit pattern. The processing module receives a bit stream corresponding to the ASG Huffman tree from an encoder. The bit pattern matching module selects bits from the bit stream according to the code length of the bit pattern and decodes the selected bits into a symbol in the ASG Huffman tree by comparing the selected bits with the bit pattern.

The conventional I/O devices of a storage element, such as memory card, have a built-in microprocessor control unit (MCU) for executing the I/O commands. The demand of MCU increases the cost. Besides, the capacity of the storage element supported by the device is depend on the firmware inside the MCU. Since the updating of firmware is a tough job, the supportability is lack of elasticity. This invention discloses a method for driving the I/O device of storage element that strengthens the device driver to get rid of the MCU. The capacity supported hence can be raised by merely updating the device driver.
