Programming of digital linear phase filter in ARMv8 architecture
We consider the problem of using processors with an ARMv8 architecture to speed up the operation of multimedia algorithms and digital processing when solving problems of signal recovery in the filtering process. As an example, the implementation of the algorithm of a digital FIR filter with a linear...

| description | We consider the problem of using processors with an ARMv8 architecture to speed up the operation of multimedia algorithms and digital processing when solving problems of signal recovery in the filtering process. As an example, the implementation of the algorithm of a digital FIR filter with a linear phase-frequency characteristic is considered. The proposed formula for calculating the filter. The algorithm is optimized using vector SIMD instructions of the ARMv8 architecture. An implementation of the C signal processing algorithm on a BCM2837 chip with an ARM Cortex-A53 processor is presented. The solution provided effective recovery of frequencies distorted when transmitting signals in the audio range and proves the efficiency of using mobile multicore ARMv8 processors for parallel data processing in solving complex computational problems. Experimental results prove that the use of ARMv8 architecture processors when solving signal filtering problems significantly speeds up multimedia and signal processing algorithms such as video encoder / decoder, 2D / 3D graphics, games, sound and speech processing, image processing, telephony and sound. |
