A multiple-processor system uses transfer blocks each having a size equal to or less than the capacity of a shared memory when transferring data from a master system to a slave system via the shared memory. Each transfer block includes a data to be transferred from the master system or a plurality of divisional data obtained by dividing the data to be transferred; information representing a writing-start address at which the data to be transferred or the plurality of divisional data starts to be written in storage for the slave system; and information representing the length of the data or the plurality of divisional data.

Multiple-processor system and method for transferring data and/or a program stored in one processor to another processor in order to process the data or to execute the program therein

A digital information reproduction apparatus for compressing frames of data so as to intermittently reproduce the data in fast-forward speed. A data re-write device retrieves a reproduction-target frame for the fast-forward reproduction and a parameter-calculation-target frame exclusively for calculation of the frame data parameters. The frames then are transferred to a RAM. A decoder determines the frame data in the RAM, calculates the parameter-calculation frame data, and decodes the reproduction frame data by use of the parameter obtained as above. The described operation prevents expending the reproduction frame data with an incorrect parameter so as to normally fast-forward reproduce the compressed data. Furthermore, the present can select a frame used in the fast forward reproduction according to a feature index so that a section subjected to the fast-forward reproduction can be easily grasped by the user.

Fast-forward/fast-backward intermittent reproduction of compressed digital data frame using compression parameter value calculated from parameter-calculation-target frame not previously reproduced

A digital information reproducing apparatus in accordance with a prior art that uses a semiconductor memory to realize a memory means cannot reproduce digital data which has been encoded according to a compression coding form different from the one adopted by an incorporated decoding circuit. According to the present invention, a decoding program stored in a second semiconductor memory is selected according to a compression coding form adopted for digital data stored in a first semiconductor memory. The selected decoding program is used to decode the digital data by means of an arithmetic circuit. Thus, digital information can be reproduced irrespective of a compression coding form adopted for provided digital information.
