摘要: An EBCOT codec (1) is provided which includes a bit modeling unit (11), arithmetic codec (12), input FIFO memory (13), output FIFO memory (14) and a controller (16). The input and output FIFO memories (13) and (14) have a function to control the bit length of to-be-stored data correspondingly to that of supplied data. For the coding, the input FIFO memory (13) is supplied with a wavelet transform coefficient of 16 bits, and for the decoding, it is supplied with a code data of 8 bits. For the coding, the output FIFO memory (14) outputs 8-bit code data, and for the decoding, it outputs wavelet transform coefficients of 16 bits. Thus, the circuit scale can be reduced and data transfer speed be improved.

摘要: A method of applying porous building plates includes applying plate-like porous building plates having pores on the surfaces and then jointing them by means of a coated joint method. In the method, the pores on the surfaces of the porous building plates are packed with an acid soluble substance and then the plates are joined by means of a coated joint method. Subsequently, the surfaces of the porous building plates are washed with an acid.
