Finally the output serial bitstream is converted back into a parallel sum. A full-adder sums the two numbers on bit at a time, carrying-in the carry bit from the previous clock cycle. Two 4-bit parallel inputs are converted to 4-bit serial bit streams with least significant bit (LSB) first. Lab2 LAB 2: Sequential logic in VHDL Bit serial adder: The above block diagram describes a digital design that demonstrates bit-serial arithmetic.

Д¬onsult the VHDL/Verilog language reference manuals for more information.Д«efore writing Shift Register behavior it is important to recall that Virtex, Virtex-E, Virtex-II, and Virtex-II Pro have specific hardware resources to implement Shift Registers: SRL16 for Virtex and Virtex-E, and SRLC16 for Virtex-II and Virtex-II Pro.

predefined shift operators for example, sll, srl.

There are different ways to describe shift registers.

parallel: the contents of one or several of flip-flops other than the last one, is accessed.

serial: only the contents of the last flip-flop is accessed by the rest of the circuit.

In general a shift register is characterized by the following control and data signals, which are fully recognized by XST:
