Implementation of CELP encoder using Vivado HLS

Eminent research scholars have confirmed the feasibility of CELP principle and its implementation which overcomes the hurdles of primitive algorithms like RELP, where in the residual signal information can't be reconstructed further, but which is possible in CELP implemented technique which produces good quality speech at low bit rates. This paper's central idea is the design and implementation of CELP encoder. This LPC technique achieves LP analysis of speech by extracting the LP parameters and coefficients and utilizes a scheme to search a codebook and compute the excitation signal. With the help of Vivado HLS we have implemented synthesizable set of codes and shown the report including timing, latency and hardware utilization.
