PURPOSE:To realize an efficient terminal processing by providing a first microcomputer section and a second microcomputer section to share a work. CONSTITUTION:A first microcomputer section 20 and a second microcomputer section 30 are connected through an interface circuit section 40. Direct memory access control circuits 24, and 34 of the respective microcomputer sections can perform an access at least RAMs 22, 32 of the other microcomputer section. On a ROM23, a main program corresponding to an essential processing is stored and on a ROM33, an input and output device control sub-program is stored. |
