REAL-TIME FAST FOURIER TRANSFORM COPROCESSOR CORE Russian patent published in 2015 - IPC G06F17/14 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to digital signal processing. The technical result of the invention is designing a real-time fast Fourier transform coprocessor core for autonomous, concurrent operation with a digital signal processor (DSP), performing fast Fourier transforms of complex arrays and certain accompanying operations, having the following advantages: input/output is carried out in real time, concurrent with processing; input/output data for an input/output data user are arranged in a direct order; no additional memory is required for calculation and storage of data in direct order; formats of real/imaginary components of input and output data: 32-bit floating point (IEEE-754 standard), 32-bit fixed point (integer, complementary code), 16-bit fixed point (integer, complementary code); computation format: 32-bit floating point; maximum size of directly executed transform - 8192 K, minimum - 16 K, limiting size of extensible transform - 256 K.

EFFECT: designing a real-time fast Fourier transform coprocessor core for autonomous, concurrent operation with a DSP.
