ABSTRACT:
An apparatus deinterleaves decoded symbols and outputs the deinterleaved symbols in an appropriate form for external devices. In order to achieve the deinterleaving and outputting processes, the apparatus sequentially stores the decoded symbols in response to enable signals and produces output data of P bits based on the stored decoded symbols by using two memory groups which alternately perform the storing and the producing processes. The operations of the two memory groups are controlled by an input control block and an output control block. The input control block produces the enable signals to control the two memory groups to thereby sequentially store the decoded symbols to the two memory groups. The output control block selects one of outputs provided from the two memory groups and provides the selected output as the output data of P bits.
