Abstract: An information processing system includes a control central processing unit a memory; and a stream interface configured to receive an input stream including data to be processed and to transfer the input stream to the memory. A download process in which the stream interface receives stream data including firmware and stores the stream data in the memory is executed in response to an instruction from the control central processing unit, and the control central processing unit analyzes the stream data stored in the memory to extract the firmware in the memory space and executes the firmware extracted in the memory space to process the data to be processed.

Abstract: A first internal resource has a first register which is accessible from an external bus via an internal bus and has a same data width as that of the internal bus which is larger than that of the external bus. A second internal resource has a second register which has a same data width as that of the external bus and is accessible from the external bus via the internal bus. A bus interface circuit implements a data transmitting operation between the external bus and the internal bus. The bus interface circuit is constituted of a write buffer and a read buffer which have a same data width as that of the external bus and are accessible from the external bus.

Abstract: A data encoding/decoding apparatus comprises a decoder which decodes a coded stream, which is formed in a first format and inputted on real time, to generate video data and audio data. A video output memory stores the video data from the decoder. An audio output memory stores the audio data from the decoder. A video input memory is provided to be connected to the decoder through a first data path when the coded stream is transcoded to generate a second stream formed in a second format. An audio input memory is provided to be connected to the decoder through a second data path when the transcoding is performed. An encoder encodes the video data from the video input memory and the audio data from the audio input memory to generate the second stream.

Abstract: An agent for cleaning and dissolving tartar or removable oral prostheses comprises a solution of a phosphonic acid base chelating agent or agents as the active agents in water, the phosphonic acid base chelating agent or agents being selected from the group consisting of aminotrimethylphosphonic acid, hydroxyethylidenephosphonic acid and ehtylenediaminetetramethylphosphonic acid as well as their alkali metal salts, and being contained in water in an amount of 15 to 90 weight %, the solution being of a pH of 7 or lower.
