Patent ID: 7818162

Claim:
An information processing device comprising a first processor for obtaining a predetermined instruction; and a second processor for executing processing by emulation in accordance with a direction from the first processor, wherein the first processor is constituted so as to direct the second processor to execute the processing by emulation in accordance with the predetermined instruction and to send the second processor data used for the processing by emulation, wherein the second processor includes: a determination means for determining whether the processing by emulation is executable based on the data sent from the first processor upon receiving the direction to execute the processing by emulation by the second processor, and when the processing by emulation is not executable by the second processor, sending a notice that the processing by emulation is not executable by the second processor to the first processor together with information generated from the data, and a second processing means for executing the processing by emulation when the processing by emulation is executable by the second processor, wherein the first processor is constituted so as to execute the processing by emulation when the notice is sent from the second processor, and wherein the first processor and the second processor are constituted so as to execute the processing by emulation together.
