Abstract

The invention discloses a pinlock hardware circuit and electronic equipment. The hardware circuit comprises a safety protection unit, an address judgment unit, a write data judgment unit, a write-in judgment unit, a read control unit and a spinlock state register unit. wherein the safety protection unit is used for monitoring whether read-write access sent by a bus is safe access sent by a CPU (Central Processing Unit) or not, if the read-write access sent by the bus is safe access, response is given, and if the read-write access sent by the bus is not safe access, an access request of the busis refused; And the address judgment unit is used for inquiring a bus write address, converting the bus write address into selection information corresponding to the to-be-accessed sink register unit, and sending a conversion result to the write data judgment unit and the write judgment unit. According to the technical scheme, a pinlock control algorithm is realized through hardware, and softwarecontrol is simple. And higher-level security protection is realized through security access control at a hardware level. Compared with software control, the speed of hardware control is higher.

Description

technical field [0001] The invention relates to the field of hardware circuits, in particular to a spinlock hardware circuit and electronic equipment. Background technique [0002] With the rapid development of multi-core processors, the processing mechanism for concurrent processing of multi-core processors is becoming more and more important. The spinlock is an important and effective mechanism to avoid errors in multi-core parallel processing. But the current spinlock processing still has obvious problems. First of all, the software control is complicated. spinlock needs to designate a storage area as the lock state storage area, and the method of using software to designate the area in the memory is complicated and not safe enough, and it is easy to be broken by hackers. And the software processing operation speed is relatively slow. Contents of the invention [0003] Therefore, it is necessary to provide a spinlock hardware circuit and electronic equipment to solve...
