PURPOSE:To avoid the trouble to set an address for each block, by recognizing the data of plural blocks of a data memory which is formed into blocks as a block of a designated address of another data memory formed into blocks. CONSTITUTION:The address groups which are transferred in order of the data memories which are formed into blocks are set by a microprocessor to a setting circuit 10 for block address group. The initial value is given to the circuit 10, and the initial address to be first transferred is set to a DMAC register 12 via a multiplexer (MPX) 11. At the same time, the number of blocks to be transferred is set via an MPX16 after the application of the initial value. Then the word component (2) is added by an adder 14 via a count-up register 13 and then returned to the MPX11, and then the address of the next word component is transferred through a DMA register 12. This procedure is repeated to complete one block. |
