PURPOSE:To reduce a load on software while increasing processing efficiency by adding a transfer function for service commands to a service processor. CONSTITUTION:An information processing system includes central processing units CUP1'-CPU3', peripheral controllers CPU1-CPU3, and service processors SVP1'-SVP3'. The central processing units CPU1'-CPU3' are connected to the peripheral controllers CPU1-CPU3 mutually. The service processors SVP1'- SVP3' are connected to the corresponding peripheral controllers PCU1-PCU3. The service processors SVP1'-SVP3' have the same constitution and each processor includes an interruption generating part 5, interruption discriminating part 6, interruption generation position recognizing part 7, and data transfer part 8 in addition to a decoding part 3 and a definition switch 4. |
