Problems solved by technology
[0002] Due to the huge difference between the processing speed and the memory reading speed of modern processors, the processing speed is much greater than the reading speed of the memory, that is, the "memory wall" phenomenon, which limits the performance improvement of modern processors
Special hardware architecture - Computational storage is an important means to solve the "storage wall" bottleneck. The existing instruction set structure only supports the hardware architecture in which the operands are in memory and registers respectively. By reading the operands in the memory to the processing After performing arithmetic and logic operations with the operands stored in the internal registers of the processor, they are written back to the memory, resulting in repeated data read and write operations, which reduces the operational efficiency

The invention discloses an optimization method and system for calculation type storage instruction set operation and a storage medium. The method comprises: determining a first instruction and a second instruction through an instruction identification code; performing mode configuration operation, address configuration operation and calculation operation on the second instruction through the sub instruction type bit of the second instruction; determining the vector length of the second instruction through the vector length bit of the second instruction; determining the operation type of the second instruction through the operation type bit of the second instruction; determining the function type of the second instruction through the function type bit of the second instruction; determiningan immediate number of the second instruction through the immediate number bit of the second instruction; obtaining an operation result of the second instruction, wherein the second instruction is a calculation type storage instruction. The method improves the operation efficiency, and can be widely applied to the technical field of instruction set design of hardware processors.
Description
technical field [0001] The invention relates to the technical field of instruction set design of hardware processors, in particular to an optimization method, system and storage medium for computing storage instruction set operations. Background technique [0002] Due to the huge difference between the processing speed and memory reading speed of modern processors, the processing speed is far greater than the reading speed of the memory, that is, the "storage wall" phenomenon, which limits the performance improvement of modern processors. Special hardware architecture - Computational storage is an important means to solve the "storage wall" bottleneck. The existing instruction set structure only supports the hardware architecture in which the operands are in memory and registers respectively. By reading the operands in the memory to the processing After performing arithmetic and logic operations with the operands stored in the internal registers of the processor, they are wr...
