Abstract

The invention relates to a data processing method, a security chip device and an embedded system, belongs to the technical field of computers, and solves the problems of low data processing rate and incapability of adapting to encryption and decryption algorithms with large calculated amount in the prior art. The method comprises the following steps: S1, storing a first data stream in a first RAM;S2, storing the second data stream in a second RAM, processing the first data stream through an algorithm unit, and storing the processed first data stream in a first RAM; S3, outputting the processed first data stream to an upper computer, processing a second data stream through an algorithm unit, and storing the processed second data stream in a second RAM; and S4, outputting the processed second data stream to an upper computer, wherein T is a data processing period. Within the same T, the number of data processing is increased, the utilization rate of algorithm units is improved, and therefore the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a data processing method, a security chip device and an embedded system. Background technique [0002] Random Access Memory (Random Access Memory, abbreviation: RAM), also called main memory, is an internal memory that directly exchanges data with the CPU. It can be read and written at any time (except when refreshing), and the speed is very fast, and it is usually used as a temporary data storage medium for operating systems or other running programs. When RAM is working, information can be written (stored) or read (taken out) from any specified address at any time. RAM is used in computers and digital systems to temporarily store programs, data, and intermediate results. [0003] Processing a set of data in the prior art requires three steps: storing the data in RAM, processing the data and reading the data from the RAM, which requires three processing cycles, therefore, si...
