Question

6: Write a C+ program (submit a CPP file or link to C++ shell URL) that implements the solution to question 2 2: A serial odd parity generator is to be designed. A binary sequence of arbitrary length is presented to the parity generator on input X. When a given bit is presented on input X, the corresponding odd parity bit for the binary sequence is to appear during the same clock cycle on output Z. To indicate that a sequence is complete and that the circuit is to be initialized to receive another sequence, input Y becomes 1 for one clock cycle. Otherwise, Y is 0. Derive the State diagram and state table

Answer 1

Generate VHDL code of odd parity generator using ModelSim simulator the entity section of the code define input part and output port Define three processes, one for the state registers, one for next state and ane for the autput. t the initial state as A n state register next state func set the next state as per the input n output furc set the value of output Z as per current state and inout. -odd parity generator -declare library library ieee; use ieen.std Jagic 1164.all -declare entity entity odd parity gen is -declare port port(CLK, RESET. : std logic; -outout port : out std Jogic) end entity end odd parity gen; -declare architecture of the entity architecture process 3 of odd parity gen is -declare state type using keryword type state type is(A.B) declare state, next state and stat type as signal signal state, next state: state type begin -state registers state_register: process (CLK, RESET) begin the process begin -use if-else statement if (RESET 1) then states A: elsif (CLK'event and CLK-1then stateeanext state; end if end process; -next state function. next state func: processX, state) begin se case statements r different states case state js when A -use if-else statement -if value of RESET is 1 then state" have value of B else it will have A if X1then next stateB: else next stateA -end the T" statement end if: when B > next state B; end case -end the process end process -output function output func: process (X, state) begin --use case statement different states case state is
