Speech Processing: LPC Exercise on TI TMS320C54x (m10825)
Keywords: autocorrelation, autocovariance, division, DSP, speech processing
Summary: You will write code to compute the autocorrelation or autocovariance of an input signal. Then you connect a microphone to the DSP and write code to detect the beginning of a speech segment. Finally, you will combine the two programs and compare results with MATLAB.

Speech Processing: Theory of LPC Analysis and Synthesis (m10482)
Keywords: autocorrelation, autocovariance, correlation, cross-correlation, DSP, levinson-durbin, linear predicitive coding, speech, speech coding, speech compression, speech synthesis
Summary: Speech analysis and synthesis with Linear Predictive Coding (LPC) exploit the predictable nature of speech signals. Cross-correlation, autocorrelation, and autocovariance provide the mathematical tools to determine this predictability. If we know the autocorrelation of the speech sequence, we can use the Levinson-Durbin algorithm to find an efficient solution ... the speech.

Two's Complement and Fractional Arithmetic for 16-bit Processors (m10808)
Keywords: DSP, fractional arithmetic, overflow, two's complement
Summary: Two's-complement notation is a mathematically convenient way of representing signed numbers in microprocessors. The most significant bit of a two's complement number represents its sign, and the remaining bits represent its magnitude. Fractional arithmetic allows one to multiply numbers on an integer processor without incurring overflow. Fractional ... one bit.
