Disclosed are a floating-point accumulation device and method and a computer storage medium. The floating-point accumulation device comprises: a loading module for reading N original floating-point numbers, and continuously outputting the N original floating-point numbers in sequence in N calculation cycles, wherein N is an integer greater than 3 (S510); a control module for judging the calculation stage of the current calculation period and controlling at least one multiplexer to send the original floating-point number output by the loading module or an intermediate result output by the output end of the floating-point addition module to the input end of the floating-point addition module according to the calculation stage (S520); and a floating point addition module for acquiring two floating point numbers at the input end in each calculation period, accumulating the two floating point numbers by adopting an M-stage pipeline structure and outputting the intermediate result or the final result at the output end, wherein M is an integer greater than 1 (S530). The device can improve the floating point accumulation speed.
Description
technical field [0001] The present invention relates to the technical field of floating point calculations, in particular to a floating point accumulation device, method and computer storage medium. Background technique [0002] A digital signal processor (Digital Signal Processor, DSP) is a chip specially used for data-intensive calculations, which contains different circuit structures to perform different functions, including the ALU for integer arithmetic and logic operations, and the FPU for floating-point operations. Wait. Floating-point numbers are widely used due to their high precision and high dynamic range. DSP has a floating-point instruction set dedicated to floating-point calculations, including basic floating-point addition, subtraction, multiplication, etc., as well as more complex multiplication and addition, Operations such as multiplication and accumulation. Floating-point addition is more complicated than integer addition. How to efficiently implement fl...
