Abstract
An information processing apparatus has an SDL execution unit described in a specification and description language (SDL), an external environment description unit described in a programming language other than the SDL, and an adapter having a pseudo internal signal generator and a queue manager. A task of an operation system is assigned to the external environment description unit, which is combined with the SDL execution unit through the adapter. The pseudo internal signal generator converts signals including messages, events, and parameters to be transferred between the SDL execution unit and the external environment description unit. The converted signals are transferred between the SDL execution unit and the external environment description unit through the queue manager. Also provided is an information processing method to materialize the information processing apparatus. These method and apparatus reduce the overhead of the operation system.
