Problems solved by technology

When batch operations are required, for example, when multiple commands need to be executed on large blocks of data, the above processing flow needs to be executed sequentially for each command and each piece of data in the large block of data. Therefore, the entire processing process is very time-consuming and inefficient

Embodiment Construction

[0021] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] First, an information processing method according to an embodiment of the present invention will be described.

[0023] The information processing method of the embodiment of the present invention is applied to a controller in a computer. Specifically, the controller can be used to control direct memory access (DMA) related operations. That is, the controller may also be called a DMA controller. Additionally, the controller is capable of communicating with a processor, such as a central processing unit (CPU).

[0024] Below, will refer to figure 1 The information processing method of the embodiment of the present invention is described in detail.

[0025] Such as figure 1 As shown, first, in step S101, the information processing method of the embodiment of the present invention receives a first auxiliary command from the processor. It should...

Abstract

The invention discloses an information processing method and information processing equipment used for a controller. The controller communicates with a processor. The information processing method includes that receiving a first auxiliary command from the processor, wherein the first auxiliary command comprises a direct memory access commanding command; responding to the first auxiliary command, and receiving a plurality of main commands from the processor in a DMA mode; responding to the main commands, and respectively executing operations corresponding to the main commands; generating interrupt signals; sending the interrupt signals to the processor.

Description

technical field [0001] The present invention relates to the field of information processing, and more specifically, the present invention relates to an information processing method and an information processing device. Background technique [0002] In an embedded system, operations such as reading and writing of large blocks of data are quite time-consuming, especially for operations on flash memory (Flash) chip particles. Taking a read command as an example, generally speaking, the operation process will include the following steps. [0003] First, the central processing unit (such as CPU) sends a read command to read the data in the Flash memory bank into the Flash cache. Next, the CPU checks whether the data is ready by querying or interrupting. When it is confirmed that the data is ready, the CPU sends a data direct memory access (DMA) command to read the data in the Flash cache (or in the controller cache) to a specified memory, such as an external DDR. After the DM...
