Embodiment 1

[0046] like figure 1As shown, the string hardware acceleration structure device (Sting Accelerator) is set on the chip, adjacent to the memory controller and the on-chip Cache. For the string comparison operation (string compare), the corresponding acceleration processing structure is set in the adjacent memory controller (DDR Controller). The corresponding accelerated processing structure for string copy is set adjacent to the on-chip first-level Cache. The reason for doing this is: 1) the goal of this device is to design a general-purpose character string processing acceleration structure, which can be integrated in a general-purpose processor, so the structure needs to be integrated on-chip; 2) because this device is aimed at big data applications, The amount of data is huge. For example, Terasort is for terabyte-level data sorting. Therefore, the design principle of this device is to place the processing device as close as possible to the main memory, and the character s...

Embodiment 2

[0053] like figure 1 As shown, the present invention is based on a traditional processor system, and adds a string processing acceleration structure 104. The string comparison operation of the acceleration structure 104 is placed next to the storage controller 103, and by directly requesting data from the storage control 103, character string processing is performed. string processing. The character string copy of the acceleration structure 104 is placed next to the first-level Cache 102, and the character string is copied by reading the Cache line data from the first-level Cache 102. The acceleration structure 104 is controlled by the instructions issued by the pipeline of the processor core 101 , and writes the result of the operation back into the processor core 101 .

[0054] The following are the specific operation steps of each functional module:

[0055] like Figure 5 As shown, it is a string comparison operation accelerator. Character comparison operation steps: ...

Abstract

The invention discloses a hardware acceleration structure device for general-purpose character string processing. The hardware acceleration structure is integrated in a general-purpose processor, controlled by special-purpose string processing instructions from the pipeline, and writes calculation and processing results back In the pipeline, the hardware acceleration structure device includes: a character string comparison acceleration structure, which is arranged next to the storage controller, and directly requests the data in the memory from the storage controller to perform comparison operation processing; a character string copy acceleration structure, which is arranged at Next to the first-level cache, data is requested directly from the first-level cache, and each time data is requested, a cache line is used as the length unit for data processing. The invention can significantly improve the execution efficiency of string operations in big data applications.

Description

technical field [0001] The present invention relates to the field of big data application and hardware acceleration technology, in particular, to a hardware acceleration structure device and control method for general character string processing. Background technique [0002] With the sharp increase in the amount of data processed by big data applications, general-purpose processors are not efficient in processing big data applications with huge amounts of data. The main reason is that traditional general-purpose processors are originally designed for scientific computing applications. , emphasizing that data complex operations are greater than data access. The main feature of rapidly developing big data applications is data access, and data calculation is simple. Therefore, it leads to the inefficiency of current general-purpose processors in processing big data applications. [0003] In big data processing applications, character operations are the most basic type of ope...
