Memory allocation method and multi-core concurrent memory allocation method

A multi-core concurrent memory allocation method, comprising a memory allocation method applied to an embedded system, wherein a kernel module and a plurality of application programs are provided;

• wherein the memory allocation method comprises steps of:
• Step S1, acquiring first memory allocation requests of the plurality of application programs;
• Step S2, the kernel module determining whether preset screening marks exist in the first memory allocation requests;
• Step S3, when screening marks exist in the first memory allocation requests, prohibiting allocating memory for the current application program managed by a contiguous memory allocator;
• wherein the multi-core concurrent memory allocation method specifically comprises steps of:
• M processing units being provided in the embedded system, when
• the second memory allocation requests sent by the driver module are received, performing steps of:
• Step B1, acquiring the quantity of contiguous memory that needs to be allocated according to the second memory allocation requests;
• Step B2, dividing the quantity of the contiguous memory allocated into N parts;
• Step B3, sending the second memory allocation requests to each of the processing units;
• and
• Step B4, allocating the quantity of the contiguous memory corresponding to each of the N parts by the each of the processing units according to the second memory allocation requests.
