Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a dynamic memory management system and method for a multi-threaded processor, so as to avoid idle kernel threads occupying more free memory at a certain moment, while kernel threads with less initial allocations need more memory. Improving the memory usage efficiency of the system when the application cannot be applied

Embodiment 1

[0046] refer to figure 2 As shown, it is a schematic diagram of division of memory pool, memory block and memory unit in the present invention. The system main memory 100 is divided into multiple memory pools 210 by the main control kernel thread, such as memory pool 0, memory pool 1 and memory pool S in the figure. Each memory pool 210 is further divided into a plurality of free memory blocks 211 , as shown in the case of memory pool 0 in the figure. In actual use, some free memory blocks 211 are occupied by kernel threads and converted into allocated memory blocks 212, which are managed and maintained by the kernel thread that obtains the allocated memory blocks 212, as shown in the case of memory pool 1 in the figure. After the kernel thread obtains the allocated memory block 212, it further divides the allocated memory block into free memory units 233. In actual use, some free memory units 233 are occupied by applications and converted into allocated memory units 234, as...

Embodiment 2

[0053] refer to Figure 4 As shown, it is a schematic diagram of a dynamic memory management system for a multi-core multi-thread processor according to the second embodiment of the present invention. The dynamic memory management system of the multi-core multi-thread processor 110 includes a plurality of kernel threads, among which there is a master kernel thread 403 , and one other kernel thread 404 is marked as an example. The main control kernel thread 403 further includes: a memory monitoring module 400 , a main control memory management module 401 , and a message processing module 402 . It can be clearly seen from the figure that the memory management module and the message processing module also run on other kernel threads at the same time, such as the memory management module 405 and the message processing module 406 running on other kernel threads 404 . Except for the kernel thread 404, the module structures of other kernel threads can be deduced in the same way, whi...

Abstract

The invention disclosed a multi-thread processor dynamic memory management system and method. The system includes a message treament module, a main control memory management module and a memory monitoring module. The method includes the steps: a main kernel thread applies to one-stage memory as a memory pool from the memory of system; all kernel threads tranmit the message for applying to the memory for main kernal thread, and main kernel thread distributes free memory in the memory pool to the kernel thread for applying to the memory after receiving the message for applying to the memory, and transmits the message for distributing the memory for the kernel thread for applying to the memory; main control kernel thread inquires the use of memory which has been applied by the kernel thread, and transmits the message of callbacking memory; the kernel thread returns the memory after receiving the medssage of callbacking memory, and transmits the message of releasing the memory for main control thread. The use of memory in the system ia able to be improved using the inventive multi-thread processor dynamic memory management system and method.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a multi-thread processor dynamic memory management system and method. Background technique [0002] With the improvement of processing power and real-time requirements, it is becoming more and more difficult for single-core processors to meet the needs of communication equipment for high-performance processing capabilities. Only by increasing the frequency and increasing the cache can only slightly improve the performance, and the ensuing is an increase in power consumption and cost. The multi-core multi-thread processor integrates two or more processing cores into one processor, thereby improving the processing capacity. Take RMI's XLR series processors as an example, this series of processors integrates up to 8 RMI-enhanced MIPS64 RISC CPU cores, each core supports 4 threads, so the XLR processor can support up to 32 threads, that is, a multi-core The processing power of the mu...
