Data loading and storage instruction processing method and device

Abstract

An instruction processing device includes a first register adapted to store a source data address, a second register adapted to store a source data length, a third vector register adapted to store target data, a decoder, and an execution unit. The decoder is adapted to receive and decode the data loading instruction. The data loading instruction indicates the first register as a first operand, thesecond register as a second operand, and the third vector register as a third operand. The execution unit is coupled to the first register, the second register, the third vector register and the decoder, and executes the decoded data loading instruction, so the source data address is obtained from a first register, and a source data length is obtained from a second register; the execution unit acquires data whose starting address is the source data address and whose length is based on the source data length from a memory coupled to the instruction processing apparatus, and stores the acquired data as target data in a third vector register. The invention further discloses an instruction processing device, an instruction processing method and a computing system for processing the corresponding data storage instruction.

Description

technical field [0001] The present invention relates to the field of processors, and more particularly to processor cores and processors having instruction sets for data load and store instructions. Background technique [0002] During the operation of the processor, data needs to be obtained from the external memory, and a large number of calculation results will also be stored in the external memory. Only by providing data for operation instructions as soon as possible and saving the results can the processor run efficiently. The load and store instruction is an instruction for the processor to move data between the register and the external storage. Data loading means that the processor moves data from the external memory to the internal register, and data storage means moving the data of the internal register to the external memory. [0003] SIMD instructions, which can perform the same operation on multiple sets of data in parallel, are widely used in the VDSP instructi...

AI Technical Summary

Problems solved by technology

The existing fixed-length data load and store instructions need to use multiple instructions to load and store data, and then perform data splicing. The flexibility of the instructions is not high; The length is different, and the appropriate fixed-length load and store instructions need to be selected according to the data length, which increases the programming complexity of the user; in addition, in the scenario that requires a large amount of data calculation, the user needs to maintain the length of the data to be processed, and according to The length adjusts the size of the data loaded and stored next time in time, which increases the difficulty of programming for users

[0004] For this reason, a new data loading and storage instruction scheme is needed, which can solve the problem that the source operands required in various data processing processes are of different lengths, fragmented, and are not conducive to the preparation of operational data.
