Online debugging and upper computer communication module of SOC (system-on-chip) chip for embedded data security system

Abstract

The invention relates to an online debugging and upper computer communication module of an SOC (system-on-chip) chip for an embedded data security system. The online debugging and upper computer communication module has the advantages that a data channel can be built between a host computer and a data security system only by a USB (universal serial bus) cable without other external equipment; the channel can be used as a 'debugging channel', and can also be used as a 'communication channel'. By the design, the complexity of the system can be lowered; the cost of the system can be reduced; the reliability of the system can be improved.

Description

technical field [0001] The invention relates to an SOC chip, in particular to an online debugging of an SOC chip for an embedded data security system and a communication module of a host computer, and belongs to the field of electronic technology. Background technique [0002] SOC is the abbreviation of System On Chip, which refers to a system on a chip, also known as a chip-level system. SOC belongs to the category of application-specific integrated circuits. It contains a variety of functional components or modules inside, has the functions of a complete system, and some functions can be embedded in software. The application and development of SOC technology will help electronic equipment to reduce volume and weight, reduce power consumption, improve reliability and reduce system cost. [0003] With the continuous improvement of the degree of informatization in modern society, all information can be transformed into data that can be recognized by computers. The character...
