Data processor

A recording medium recording thereon a control program comprising an instruction set including:

• a first field for describing an execution instruction for designating content of an operation or data processing that is executed in at least one processing unit forming a data processing system;
• a second field for describing preparation information for setting the processing unit to a state that is ready to execute the operation or data processing that is executed according to the execution instruction, the preparation information in the second field being for the operation or data processing that is independent of the content of the execution instruction described in the first field of the instruction set;
• and
• a third field for indicating, independently of the first field, valid/invalid of the second field and a type of the preparation information.

A transmission medium having embedded therein a control program comprising an instruction set including;

• a first field for describing an execution instruction for designating content of an operation or data processing that is executed in at least one processing unit forming a data processing system;
• a second field for describing preparation information for setting the processing unit to a state that is ready to execute the operation or data processing that is executed according to the execution instruction, the preparation information in the second field being for the operation or data processing that is independent of the contents of the execution instruction described in the first field of the instruction set;
• and
• a third field for indicating, independently of the first field, valid/invalid of the second field and a type of the preparation information.

A data processing system, comprising:

• at least one processing unit for executing an operation or data processing;
• a unit for fetching an instruction set including a first field for describing an execution instruction for designating content of the operation or data processing that is executed in the processing unit, and a second field for describing preparation information for setting the processing unit to a state that is ready to execute the operation or data processing that is executed according to the execution instruction;
• a first execution control unit for decoding the execution instruction in the first field and proceeding with the operation or data processing by the processing unit that is preset so as to be ready to execute the operation or data processing of the execution instruction;
• and
• a second execution control unit for decoding the preparation information in the second field and, independently of content of the proceeding of the first execution control unit, setting a state of the processing unit so as to be ready to execute an operation or data processing.

A method for controlling a data processing system including at least one processing unit for executing an operation or data processing comprising:

• a step of fetching an instruction set including a first field for describing an execution instruction for designating content of the operation or data processing that is executed in the processing unit, and a second field for describing preparation information for setting the processing unit to a state that is ready to execute the operation or data processing that is executed according to the execution instruction;
• a first control step of decoding the execution instruction in the first field and proceeding with the operation or data processing by the processing unit that is preset so as to be ready to execute the operation or data processing of the execution instruction;
• and
• a second control step of decoding independently of the first control step, the preparation information in the second field and setting a state of the processing unit so as to be ready to execute the operation or data processing.

A control program product comprising an instruction set including:

• a first field for describing an execution instruction for designating content of an operation or data processing that is executed in at least one processing unit forming a data processing system;
• a second field for describing preparation information for setting the processing unit to a state that is ready to execute the operation or data processing that is executed according to the execution instruction, the preparation information in the second field being for the operation or data processing that is independent of the content of the execution instruction described in the first field of the instruction set;
• and
• a third field for indicating independently of the first field, valid/invalid of the second field and a type of the preparation information.
