ABSTRACT:
The invention is directed to decreasing a circuit size of a system in which a plurality of devices or circuit blocks share and use one memory. A system is configured so that a memory block serves as a master and each of circuit blocks serves as a slave, and thus the slave side (the circuit blocks) receives necessary data from the memory block by only having decoders corresponding to addresses assigned thereto in advance and registers. In this case, since the registers have been also needed in a conventional system in order to hold data read out from a memory, the circuit size decreases in the whole system. Since this effect is enhanced in proportion to the number of the circuit blocks sharing the memory block, the effect is enhanced as the system size increases.
