Title:
PROCESSOR SUPPORTING HIGH-THROUGHPUT MULTI-PRECISION MULTIPLICATION
Document Type and Number:
WIPO Patent Application WO/2022/121090
Kind Code:
A1
Abstract:
The present invention provides a RISC-V general-purpose processor supporting high-throughput multi-precision multiplication. The processor comprises an independent multiplier data path. The multiplier data path enables a data path of a multi-precision multiplier to be separated from data paths of other arithmetic units, and multi-precision instructions, after an execution stage, directly enter a register write-back stage without needing to pass through a memory access stage, thereby reducing the use of pipeline registers and saving area and power. The multi-precision multiplier has an independent data path for writing a floating-point multiplication result into a vector register file (VRF). The RISC-V general-purpose processor supporting high-throughput multi-precision multiplication in the present invention can efficiently process multi-precision computations.
