Method and architecture capable of programming and controlling access data and instructions

摘要

A method and an architecture capable of programming and controlling access of data and instructions are provided. There are provided a plurality of data transfer levels, in which a current data transfer level is used for accessing data and instructions from an external memory. Each data transfer level corresponds to a length of a continuous data transfer via an interface between the memory and a high-speed access device. The current data transfer level is dynamically adjusted based on data format accessed by a processor kernel or a result of instruction decoding performed by the processor kernel.
