An apparatus for executing instructions of a program

摘要

The invention relates to a data processing apparatus for executing instructions of a program having a first instruction decoder, an address decoder, a plurality of computational units, and an execution logic unit. The data processing apparatus is characterized in that said first instruction decoder discriminates whether said apparatus is to execute a referential instruction which initiates execution of an instruction of a different type. The invention further relates to a method of executing instructions for a data processing apparatus which method is characterized in that upon decoding a referential instruction the steps of fetching an instruction of a different type according to information included in a referential instruction and decoding said instruction of said different type for determining the operations to be executed in parallel are carried out.
