Abstract

A computer device and a method for reading or writing data by a computer device are provided. In the computer device, a central processing unit (CPU) is connected to a cloud controller using a double data rate (DDR) interface. Because the DDR interface has a high data transmission rate, interruption of CPU can be avoided. In addition, the CPU converts a read or write operation request into a control command and writes the control command into a transmission queue in the cloud controller. Because the cloud controller performs a read operation or a write operation on a network device according to operation information in the control command, after writing the control command into the transmission queue, the CPU does not need to wait for an operation performed by the cloud controller and can continue to perform other processes.

Claims20

Dependent claims

A computer device, comprising a central processing unit (CPU) and a cloud controller;

wherein the cloud controller comprises:
a memory storing a transmission queue and a response queue;
a double data rate (DDR) interface connecting the CPU to the cloud controller;
and
a network interface connecting the cloud controller to a network device;
and,
wherein the CPU is configured to:
convert a request to perform an operation on the network device into a control command;
and
write, through the DDR interface, the control command into the transmission queue in the cloud controller, wherein the control command instructs the cloud controller to perform the operation on the network device, and the control command carries operation information of the operation;
and, wherein
the cloud controller is configured to:
perform the operation on the network device according to the operation information in the control command when the control command in the transmission queue is triggered;
receive a response from the network device;
and
write the response into the response queue;
and
the CPU is configured to be able to execute another task before receiving the response from the response queue.
