Processing apparatus and processing method

A composite scalar instruction, comprising:

• an opcode field, an operand address field, and a destination address field,
• wherein an opcode stored in the opcode field indicates operations of different types,
• wherein the operand address field indicates types of operands, and
• wherein the target address field is an address where a computation result is stored,
• wherein the composite scalar instruction is an instruction that combines a floating-point instruction and a fixed-point instruction,
• wherein a data type is determined according to an address in an address field of the operand upon computation,
• wherein an opcode stored in the opcode field is used for distinguishing operations of different types,
• wherein the operand address field is used for distinguishing types of operands, and
• wherein the target address field is an address where a computation result is stored.

A method for supporting a composite scalar instruction comprising:

• storing, by a storage circuit, a composite scalar instruction and multiple types of data, wherein the multiple types of data are respectively stored in different addresses in the storage circuit in accordance with the types;
• reading, by a controller circuit, the composite scalar instruction from the storage circuit;
• decoding, by the controller circuit, the composite scalar instruction into a control signal;
• receiving, by a computing circuit, the control signal from the controller circuit;
• reading, by the computing circuit, data from the storage circuit;
• determining, by the computing circuit, a data type according to an address of the read data;
• and
• processing by the computing circuit, the read data.
