Method for execution of bus controller, computer device and storage medium

A computer device, comprising a memory and a processor, the memory storing a computer program, wherein the processor implements blocks of a method for execution of a bus controller in response to executing the computer program, the bus controller is connected to a target device by means of a target bus, the bus controller comprises an instruction memory, the instruction memory is used to store at least one instruction, the instruction corresponds to one or more bus sub-operations, and wherein the method comprises:

• in response to receiving an instruction execution command, acquiring a target instruction of the at least one instruction from the instruction memory;
• parsing the target instruction and then executing one or more corresponding bus sub-operations;
• executing a corresponding control or data operation on the target device by means of the one or more bus sub-operations,
• wherein, the bus sub-operation comprises sending reset timing, sending operation start timing, sending an operation command, sending a read and write flag bit operation, sending an address operation, sending a data operation, sending operation end timing, receiving a response bit operation, and receiving a data operation.

A non-transitory computer-readable storage medium, storing a computer program, wherein the computer program implements blocks of a method for execution of a bus controller in response to being executed by a processor, the bus controller is connected to a target device by means of a target bus, the bus controller comprises an instruction memory, the instruction memory is used to store at least one instruction, the instruction corresponds to one or more bus sub-operations, and wherein the method comprises:

• in response to receiving an instruction execution command, acquiring a target instruction of the at least one instruction from the instruction memory;
• parsing the target instruction and then executing one or more corresponding bus sub-operations;
• executing a corresponding control or data operation on the target device by means of the one or more bus sub-operations,
• wherein, the bus sub-operation comprises sending reset timing, sending operation start timing, sending an operation command, sending a read and write flag bit operation, sending an address operation, sending a data operation, sending operation end timing, receiving a response bit operation, and receiving a data operation.

A method for execution of a bus controller, wherein the bus controller is connected to a target device by means of a target bus, the bus controller comprises an instruction memory, the instruction memory is used to store at least one instruction, the instruction corresponds to one or more bus sub-operations, and wherein the method comprises:

• in response to receiving an instruction execution command, acquiring a target instruction of the at least one instruction from the instruction memory;
• parsing the target instruction and then executing one or more corresponding bus sub-operations;
• executing a corresponding control or data operation on the target device by means of the one or more bus sub-operations,
• wherein the bus controller comprises registers, the registers comprise a control register, a status register, a bus configuration register, an instruction operand register, a storage control register, and an interruption register.
