With neat figures, explain the architecture of TMS320C6713 processor.
(b) Realize the linear phase filter having the frequency response $\mathrm{h}(\mathrm{n})=\delta(\mathrm{n})-(1 / 4) \delta(\mathrm{n}-1)+(1 / 2) \delta(\mathrm{n}-2)+(1 / 2) \delta(\mathrm{n}-3)-(1 / 4) \delta(\mathrm{n}-4) +\delta(\mathrm{n}-5)$.
(b) Obtain direct form-1 and direct form-2 realization of the filter with transfer function $\mathrm{H}(\mathrm{z})=0.5\left(1-\mathrm{Z}^{-2}\right) /\left(1+1.3 \mathrm{Z}^{-1}+0.36 \mathrm{Z}^{-2}\right)$ OR
