Efficient Implementation of Parallel Self-Timed Adder Using Verilog HDLMany pipelined adaptive signal processing systems are subject to a trade-off between throughput and signal processing performance incurred b
The Verilog codes have been synthesized using 90 nm technology library. We observed that the multiplier using Kogge-Stone adder in the final stage gives higher speed and lower Power Delay Products when compared to that using Brent-Kung and Han-Carlson adders.BHARAT KUMAR POTIPIREDDI...
verilog code for for conventional tree multipliers, subword- parallel tree multipliers, and SPMSSUs using the tech- niques presented in this paper, using the Synopsys Module Compiler and LSI Logic’s G11 0.18 micron CMOS stan- dard cell library. Table 1 shows area and delay estimates for 32-...
This adder can also be used for add instructions. Repeating the pseudo code examples of combined-function operations provided above, and lining up references input operands A, B and C (and outputs X and Y) to the operand inputs (and operation results) shown in FIG. 7, it can be seen ...
When the 9-bit byte shifted out of buffer 164 is a loop instruction (LOOP-- INST) logic circuit 169 responds by pulsing a C5 control signal that causes the current address output (ADDR) of adder 170 to be stored in a register 171. The last eight bits of LOOP-- INST output of buffer...
For Doing the Study of parallel Prefix adders we use Verilog HDL for the function description and then mapped the functionality on FPGA technology library using ISE14.5. The experimental results based on the design and constraints explains that the performance of Ladner fischner adder is better ...
This brief presents a parallel single-rail selftimed adder. It is based on a recursive formulation for performing multibit binary addition. The operation is parallel for those bits that do not need any carry chain propagation. Thus, the design attains logarithmic performance over random operand ...
The parallel multipliers of the present invention, in one embodiment, require one fewer stage of reduction than conventional multipliers proposed by Wallace and Dadda. Accordingly, fewer adder components are required. The speed of the parallel multipliers of the present invention is also improved due ...
(cycle2). Nevertheless, thread #3hits (cycle3) and its token is sent to adder64(cycle4), while token32form thread #2is moved from L1 cache60to L2 cache66. Thread #3will thus reach multiplication node68in the following cycle (not shown), and the execution of thread #3will bypass ...
