摘要: When an error is detected in an error detecting unit in a processor system, the error detecting unit outputs an error signal to an interrupt control unit, and the interrupt control unit outputs a value of an error address register and a control signal to a program counter control unit and rewrites a value of a program counter to a value of an error address register. By this means, the branching process by an error interrupt is realized. In this case, when the error is detected, the process of saving the value of the program counter at the time of error occurrence is not performed, and a specific save register and a control circuit for the recovery to the address at the time of the error occurrence after the end of the error processing are not provided.

摘要: To provide a technique to reduce power consumption when carrying out image processing by processors. For the purpose of this, for example, a means for specifying a two-dimensional source register and destination register is provided in an operand of an instruction, and the processor includes a means which executes calculation using a plurality of source registers in a plurality of cycles and obtains a plurality of destinations. Moreover, in an instruction to obtain a destination using a plurality of source registers and consuming a plurality of cycles, a data rounding processing part is connected to a final stage of a pipeline. With such configurations, the power consumed when reading an instruction memory is reduced by reducing the access frequency to the instruction memory, for example.
