Chip

Abstract

The invention provides a chip. The chip comprises an internal clock module, a sleeping and awakening module and a dynamic clock regulation module, wherein the internal clock module is used for generation of an internal clock signal of the chip; the sleeping and awakening module is connected to the internal clock module and used for controlling the internal clock module to proceed to a sleeping mode or awakening the internal clock module; and the dynamic clock regulation module is connected to the internal clock module and used for regulating a clock frequency of the chip. According to such design of the chip, under the condition of completely not reducing encryption performance, deep sleeping and rapid awakening functions are added, host software completely does not need to intervene, anycomplexity of main control hardware and software cannot be increased, all the operation is automatically completed; in the common communication process, the working frequency is relatively low, so that power consumption can be saved; and in the operation encryption process, the frequency of a clock can be automatically regulated to a high frequency, and operation encryption is guaranteed to be completed in regulated time.

Description

technical field [0001] The invention relates to the technical field of chip design, in particular to a chip. Background technique [0002] Encryption chips are applied to many electronic systems to protect software / hardware design, protect data security, etc. However, current encryption chips, such as ATMEL, Maxim, etc., mainly focus on encryption algorithms and ignore power consumption. Since the power consumption of the encryption chip is generally not large, there was no need for particularly low power consumption in the past. However, modern new electronic systems are mainly portable devices, such as mobile phones, tablets, and handheld game consoles. These battery devices are very concerned about power consumption. Therefore, at present, the power supply of the encryption chip can only be cut off when it is not communicating with the encryption chip. This method will increase the hardware cost and increase the difficulty of software design. [0003] Therefore, in view...

However, modern new electronic systems are mainly portable devices, such as mobile phones, tablets and handheld game consoles. These battery devices are very concerned about power consumption.

Therefore, at present, it can only cut off the power supply of the encryption chip when it is not communicating with the encryption chip. This method will increase the hardware cost and increase the difficulty of software design.
