Method and device for constructing memory command sequence

Abstract

Embodiments of the present invention provide a method and device for constructing a memory command sequence, a storage medium, and an electronic terminal. When the estimated length is less than or equal to the length of the remaining storage space in the circular queue, the first command sequence is constructed in the pre-read cache according to the user's request, and the first command sequence is stored in the circular queue, and the command sequence contains multiple subcommands When writing a subcommand in the circular queue, it is avoided to judge whether the end address is reached once, which reduces the load of the CPU, thereby improving the operating efficiency of the CPU.

Description

technical field [0001] The present invention relates to the technical field of memory, in particular to a method and device for constructing memory command sequences, a storage medium and an electronic terminal. Background technique [0002] Currently, the CPU reads tail, head, start, and end information, calculates the size of the free buffer, and evaluates whether the current command sequence can be loaded. If so, assign tail to a temporary pointer, then organize the first subcommand, and place it in the In the queue, judge whether the next position is out of bounds, if not, move the temporary pointer to the next position, otherwise move to the start position, continue to organize the second subcommand, and so on, until the entire sequence is written. [0003] Frequently judging whether the end of the command queue is reached, and in order to organize the operation of subcommands, the pipeline behavior of the CPU will be interrupted. For the CPU, each subcommand write is a...

Problems solved by technology

Compared with the CPU, the command queue is an external structure. Depending on the bus used between the two, the CPU access speed varies, and the memory access efficiency is low compared to the internal memory of the CPU.
