Data reading method, system on chip and computer equipment

Abstract

The invention provides a data reading method, a system-on-chip and computer equipment, the method is applied to the system-on-chip, the system-on-chip comprises a first processor core, a direct register access module and at least one state register, and the direct register access module, the first processor core and the at least one state register are connected through a bus; the direct register access module comprises a first cache and a second cache; the method comprises the following steps: a direct register access module stores data read from each state register in the ith round to a corresponding target cache, and sends an interrupt signal to a first processor core, so that the first processor core reads the data from the direct register access module; i is a positive integer; wherein the target cache is one of the first cache and the second cache, and the target caches corresponding to every two adjacent rounds are different. According to the method, the resource consumption of reading the data in each state register by the processor core of the system-on-chip can be reduced, and the reading efficiency is improved.
