Loopback structure of processor and data loopback processing method

Abstract

The invention discloses a loopback structure of a processor and a data loopback processing method. The loopback structure comprises a register file unit, a data storage unit and a data reading unit, wherein the register file unit is used for providing data reading and writing service for the data storage unit and the data reading unit; the data storage unit is connected with a register file unit and is used for reading data from a reading interface of the register file unit and feeding back the read data after being data conversion to the data reading unit; and the data reading unit is connected with a register file unit and a data storage unit and is used for converting data fed back by the data storage unit and writing the data into the register file unit through the register file unit. According to the invention, the efficiency of a processor can be improved, and the power consumption of the processor can be reduced.

Description

technical field [0001] The invention relates to the field of processor architecture design, in particular to a processor loopback structure and a data loopback processing method. Background technique [0002] The processor is the core component of the chip. The efficiency and power consumption of the processor greatly affect the efficiency and power consumption of the entire chip. Therefore, in the design of the processor architecture, it is necessary to consider how to improve the efficiency of the processor and reduce the power consumption. The power consumption of the processor. [0003] Such as figure 1 As shown, in the traditional processor architecture, the following three data channels are provided: [0004] Channel 1: the data channel via "memory → data reading unit → register file unit"; [0005] Channel 2: The data channel via "register file unit → arithmetic unit → register file unit", which is also called the front door channel; [0006] Channel 3: the data c...

AI Technical Summary

Problems solved by technology

Since the operation of the memory will consume the power consumption and time of the processor, in this case, if the processor frequently reads and writes the memory, it will have a great impact on the efficiency and power consumption of the entire processor.
