Hi You can Booth-2 Algorithm for the multiplication and to sum the partial products use fast adders like Carry Select or Carry Propagate or combination of both the adders. These methods increase the speed of the multiplier computation. I think there are several other techniques are also available with proper research you can design fast (...)
The long answer is :- It depends. What resolution do you require the result to be? Are you OK with a rounded integer result? How fast do you need the result? (Single clock, multiple clocks?). Do you have a spare multiplier in your fabric? If you can come back with some answers, then I may have some idea's, but be warned - division can be a real p
i am studying me- VLSI DESIGN.i am very much interested in numerical strength reduction in the complex multiplier using fast convolution such as cook toom algorithm
Your rectifier is going to dissipate close to 2W (.6V forward drop x 3A) I think there's also a 1.4 time multiplier for bridges, I can't remember where that's from. You should check the gate drive rise time. You want it to go from 0 to max as fast as possible so the MOSFET doesn't linger in the linear region. As the MOSFET transitions from fu
Hi, I am trying implement a new multiplier accumulator unit (MAC) architecture in FPGA. Its quiet fast. But I need an application which utilizes this MAC. I need to compare its performance with the usual MAC architecture. Give me some application which will push the MAC to its limits. Thanks
First you must start with thinking through any specifications and purpose. What values, ow fast, how big, etc. You have provided absolute none information that may lead to a solution. It's pretty much like - I want to build my own car. Where do I start and how to do it?
can anyone help me in finding synthesizable codes for fast adders and fast multiplier? ,i need them for using in a convolution function.
does anyone have verilog code for booth radix-2 multiplier in verilog.i designed it,but it isn't fast and it have a lot of gates more than efficient.i khnow that for a faster booth multiplier i nedd to add CSA and compressor to it(or other adders like wallace tree),so does anyone help me with giving a fast (...)
I have heard about booth multiplier it is a fast algorithm (by using a two's complemnt addition and right shifts) used for multiplying bianary numbers but what do you mean by radix-4 and radix-8 in it....Please correct me if I am wrong some where....
Those ns numbers seem too slow. How fast do you need it to go? Which speed version chip are you using? How many bits of the multiplier are you using? Normally you want to rearrange the arithmetic to use pipelining. If you show us example test code that can be compiled, maybe someone can suggest improvement.
For a fast multiplier ,use Radix-4 partial product generator and CSA adders..
The Spartan3 has dedicated fast multipliers. If your design multiplies two 18-bit (or smaller) signed numbers, WebPack will use one of the dedicated multipliers instead of trying to synthesize it from the logic fabric (unless you override that feature). If you have more than 18 bits, WebPack will cascade several multiplier (...)
"Infer" means to use the * operator in your HDL. It is very convenient and fast, if you pipeline carefully. If you explicitly place a "MULT18X18", then you are instantiating, not inferring. The HDL compiler does the inferring. If you use XST then read the XST User Guide -> HDL Coding Techniques -> Arithmetic Operations -> multipliers. Also
I have lots of signed multiplication in my design. multiplier given by buildgates are not fast enough. can i select different multiplier in buildgates?? or i have to write my own multiplier?? Thanks Bajaj
