摘要： A method of controlling a cache memory that is connected to a main memory with a first address space and capable of acting as a random access memory, which is executed by a computer that accesses the main memory through the cache memory, comprising the steps of: determining whether the cache memory is acting as the random access memory; and assigning a second address space, which is separate from the first address space of the main memory, for the cache memory when the cache memory is acting as the random access memory.

摘要： The present invention provides a processor system having a main processor that efficiently executes coprocessor instructions, regardless of the type of each coprocessor to which the main processor is connected. When a coprocessor instruction to instruct execution by a coprocessor is supplied, the main processor determines whether or not the supplied coprocessor instruction has a possibility of having control dependency on a preceding coprocessor instruction being executed by a corresponding one of the coprocessor, in accordance with an instruction field corresponding to the supplied coprocessor instruction. If the supplied coprocessor instruction has the possibility of having the control dependency, the main processor issues the supplied coprocessor to the corresponding one of the processors only after the execution of the preceding coprocessor instruction is completed.

摘要： The control section of an information processing apparatus is set to a mode of execution of an application- specific operation. When an interruption processing program has been started after interrupting the execution of a program, a context is saved, and thereafter it is confirmed whether the operation mode has been set to a state that an operation exception that occurs during the execution of an application- specific operation instruction is detected or not. When an operation exception has been detected, an application- specific operation exception processing is carried out. Then, the context is restored, and the processing returns from the interruption.

摘要： Apparatuses and methods for interrupting the execution of a program are disclosed.
When a normal interrupt occurs, data of processor operation before the normal interrupt are held in a normal return address register (452), a normal previous state register (453), and a normal factor register (454). When a break-interrupt occurs, data of processor operation before the break-interrupt is held in another break return address register (455). Hence, a break-interrupt can occur even within an interrupt inhibition period by a normal interrupt.
A control section (433) determines whether or not a condition of a conditional instruction is satisfied and controls break-interrupt processing in accordance with a determination result.
