    摘要: An device and method for variable length decoding. The device comprises a device for variable length decoding comprising a first register, a second register, a first barrel shifter, a buffer, a coding table and an adding device. The method is characterized in that the buffer is installed on the output path from the barrel shifter to the coding table so as to shorten the critical path.

    摘要: A device and a method of sharing IDCT are disclosed. Firstly, a data word and an identifier for representing which one of several formats are extracted from a received word. Then the data word is treated with IDCT to be a signed word afterward. Then the signed word is transformed into a formatted word between the values of a maximum value and a minimum value. The data word and identifier can be received by a word receiving means and treated with IDCT by an IDCT means to generate a signed word. The signed word is transformed into a formatted word for outputting via a word transforming means. Such that words with different formats can be treated with a sharing IDCT to save the redundant cost.

    摘要: A method for accessing digital data information is used for reducing accessing time when a processor accesses digital data from a register. The method comprises the steps of accessing data from a register with a processor, continuously accessing data from the register with the processor if the data in the register is valid, enabling an identifier register with the processor if the data in the register is invalid, transmitting an interrupt signal to the processor, disabling the identifier register with the processor, and accessing the data from the register with the processor.

    摘要: A chip with IDE host and IDE slave and corresponding self-debugging function is provided. The chip simplifies IDE debugging of a chip, which comprises a front-end and a backend, by offering separate debugging modes for an IDE host and an IDE slave on the same chip. The front-end provides output data of an internal IDE slave or output data of an external IDE slave in response to a host debug enable signal. The backend is coupled to the front-end. The backend provides functions of an internal IDE host according to the output data of the internal IDE slave or the external IDE slave, or directs the output data of the internal IDE slave to an external IDE host in response to a slave debug enable signal.

    摘要: A magneto-resistive memory system is presented that includes a radiation-hardened and low power memory cell. The magneto-resistive memory cell includes a word line select transistor in the cell to help eliminate unselected cell disturbances. Furthermore, the magneto-resistive memory cell includes a full-turn write word line that writes true and complimentary bit values using less current than previous cell architectures. The improved memory cell may be used in a memory system with precision current drivers and auto-zero sense amplifiers in order to further lower power and improve overall system reliability.
