Manchester code is a coding scheme used to represent a bit in a data stream. A 'O' value of a bit is represented as a 0-to-1 transition in which the lead half is 'O' and the remaining half is '1'. Similarly, a '1' value of a bit is represented as a 1-to-transition, in which the lead half is 'l' and the remaining half is 0 For example, for the input string "110", the output is translated as: 110...

Exercises: 1. Write the VHDL statements to describe a 4-bit comparator. Use the appropriate relational operators. Use input ports A and B, described above, as the inputs to the 4-bit comparator. Assume that three output ports, EQ, GT, and LT, have been declared in the Entity statement. Use them as the outputs from the comparator 2. Identify the package (or packages) that must be included in your VHDL code in order to use the relational operators with signals of type...

Show synthesizable VHDL code for a register unit that performs operations shown below. The unit has a 3-bit mode (md) input, an asynchronous reset (rs) input, a 1-bit output control (oc) input, and an 8-bit bi-directional io bus. The internal register drives the io bus when oc is ‘I, and md is not “11 1".
