A complex computing device, a complex computing method, an artificial intelligence chip and an electronic apparatus are provided. An input interface receives complex computing instructions and arbitrates each complex computing instruction to a corresponding computing component respectively, according to the computing types in the respective complex computing instructions Each computing component is connected to the input interface, acquires a source operand from a complex computing instruction to perform complex computing, and generates a computing result instruction to feed back to an output interface. The output interface arbitrates the computing result in each computing result instruction to the corresponding instruction source respectively, according to the instruction source identifier in each computing result instruction.

Input and output interfaces for transmitting complex computing information between AI processors and computing components of a special function unit

Example embodiments of the present application provide an instruction executing method and apparatus, an electronic device, and a computer-readable storage medium that may be applied in the field of artificial intelligence. The instruction executing method may include: executing an instruction sequence that includes memory instructions and non-memory instructions, the instructions in the sequence executed starting to be executed in order; determining that execution of a first memory instruction needs to be completed before a second memory instruction starts to be executed, the second memory instruction being a next memory instruction following the first memory instruction in the instruction sequence; and executing non-memory instructions between the first memory instruction and the second memory instruction without executing the second memory instruction, during a cycle of executing the first memory instruction.

Instruction executing method and apparatus, electronic device, and computer-readable storage medium

The disclosure discloses a method for executing instructions, a device and a computer readable storage medium. The detailed implementation includes: obtaining a first memory access instruction for execution, in which the first memory access instruction includes a first address range of a memory to be accessed; in response to detecting a predetermined instruction for monitoring an accessed address range of the memory, executing the predetermined instruction to obtain a remaining address range not accessed by the first memory access instruction in the first address range; comparing the remaining address range with a second address range included in a second memory access instruction to be executed; and suspending execution of the second memory access instruction in response to the remaining address range at least partially overlapping with the second address range.

Method for executing instructions, device, and computer readable storage medium

A method and an apparatus for authenticating a chip are provided and a computer storage medium is also provided. The method may include configuring a software environment and a hardware environment associated with the chip via a configuration file, the configuration file including a plurality of instructions and data required to execute the instructions, the software environment and the hardware environment being created based on the chip; causing a plurality of instructions to be executed in a software environment and a hardware environment, respectively; obtaining a first information generated by executing instructions in a software environment and a second information generated by executing instructions in the hardware environment, respectively, the first information and the second information including the plurality of instructions being executed, its address, and data generated by executing the instructions; and authenticating the chip based on the generated first information and second information.

Method, apparatus and computer storage medium for authenticating chip

An instruction prefetching method, a device and a medium are provided. The method includes the following: instructions in a target buffer are precompiled before a processor core fetches a required instruction from the target buffer corresponding to the processor core; if it is determined that a jump instruction exists in the target buffer and a jump target instruction corresponding to the jump instruction is not cached in the target buffer according to a precompiled result, the jump target instruction is prefetched from an icache into a candidate buffer corresponding to the processor core to wait for the processor core to fetch the jump target instruction from the candidate buffer; the target buffer and the candidate buffer are alternately reused during instruction prefetching.

Method and apparatus for instruction prefetching with alternating buffers and sequential instruction address matching

A caching device, an instruction cache, a system for processing an instruction, a method and apparatus for processing data and a medium are provided. The caching device includes a first queue, a second queue, a write port group, a read port, a first pop-up port, a second pop-up port and a press-in port. The is configured to write cache data into a set storage address in the first queue and/or the second queue; the read port is configured to read all cache data from the first queue and/or the second queue at one time; the press-in port is configured to press cache data into the first queue and/or the second queue; the first pop-up port is configured to pop up cache data from the first queue; and the second pop-up port is configured to pop up cache data from the second queue.

Caching device, cache, system, method and apparatus for processing data, and medium

Embodiments of the present disclosure relate to a data access method and apparatus, an electronic device, and a computer-readable storage medium. The method may include, in response to receiving a first access request sent from a first access device in a set of access devices to a first storage device in a set of storage devices, sending an updated first access request to the first storage device, the first access request including identity information of the first access device. The method may further include, in response to receiving data from the set of storage devices, determining identity information included in the data. The method may further include, in response to the determined identity information being corresponding to the identity information of the first access device, sending the data to the first access device.
