Abstract
Information processing systems including a plurality of integrated circuit chips have had problems such as an increased cost due to an increase in the number of terminals related to settings of an interface between the chips and delayed program transfer. An information processing system is provided in which a plurality of integrated circuit chips each include a plurality of communication units to be initialized by a common setting terminal. A processing execution unit of a first integrated circuit chip set to a first mode starts establishing a communication connection through one of the initialized communication units to one of the communication units of a second integrated circuit chip set to a second mode.
Claims10
An information processing system comprising:
- a plurality of integrated circuit chips each including
- a processing execution unit that executes information processing in accordance with a program, and
- a communication unit that is caused by the processing execution unit to communicate with another one of the integrated circuit chips;
- and
- a mode setting unit capable of setting each of the integrated circuit chips to at least a first mode or a second mode,
- wherein each of the plurality of integrated circuit chips includes a plurality of the communication units to be initialized by a common setting terminal, and
- the processing execution unit of a first integrated circuit chip set to the first mode starts establishing a communication connection through one of the initialized communication units to one of the communication units of a second integrated circuit chip set to the second mode.
A communication control method for an information processing system including
- a plurality of integrated circuit chips each including
- a processing execution unit that executes information processing in accordance with a program, and
- a communication unit that is caused by the processing execution unit to communicate with another one of the integrated circuit chips:
- and
- a mode setting unit capable of setting each of the integrated circuit chips to at least a first mode or a second mode, the communication control method comprising:
- initializing a plurality of the communication units included in each of the plurality of integrated circuit chips with a common setting terminal;
- and
- with the processing execution unit of a first integrated circuit chip set to the first mode, starting establishing a communication connection through one of the initialized communication units to one of the communication units of a second integrated circuit chip set to the second mode.
