below is a 8-bit shift and add multiplier code in vhdl. u can take it as reference and design a 16-bit multiplier. --------------------------------------------------------------------------- -- The multiplier --------------------------------------------------------------------------- (...)
First, if you are intending to use a fractional fixed notation like xxx.xxx, then you can perform multiplication by shifting each operand to the left by 8 and consider them as integers .Then, you can perform integer multiplication which can be performed by "*" .After finishing the multiplication, you must (...)
i want to do following calculation in C... multiply by .62536 multiply by 9.46344 can any one suggest >>,<< method to solve this prob. ex: for .62536, =(((x <<2)+3)/6) any comments are welcome!! :D:
You can just use the built in VHDL multiply operator, *. The synthesizer can convert this to the appropriate multiplier.
Hi, I am working on a school project. I need to be able to multiply two matrices together. The values in the matrices are all signed digits. I need to multiply two matrices like this and add each value to an offset of : X X X = *
Is this * operator synthesizable? Yes, if your design compiler supports it. The multiplications in many RTLs are done by shift operators. You mean a multiplication with 2^n? In the general case (multiplying two variables) , a multiply can't be replaced by simple shift operations.
Fact - one of the most important hardware blocks in DSP cores is the MAC (multiply accumulate) unit. Assumption - the simple "shift and add" algorithm is too slow and therefore isn't utilized. Question - what is the most common algorithm used today for implementing modern (...)
Which language are you planing to use? In C this is easy if you do not have a problem with codesize ... In assembler this will not be sooo easy. In Assembler you could work like this: shift your two bytes number (that you want to multiply by 4095) 4 bits to the left (which is a multiplication by 16) now you have a three bytes result. Now
hi, fft operation is basically a repetitive multiply and add operation.There are certain stages depending on the length of the input vector. In the computation of each stage,one bit is increased in the resulting data. In the fix point calculation, this will overflow the data registers. To avoid this overflow of data (...)
Hi Naisare, multiply by 0,4 and add 1 volt dc. on1aag.
How does this work? Math Problem 1. Grab a calculator. (you won't be able to do this one in your head) 2. Key in the first three digits of your phone number (NOT the area code) 3. multiply by 80 4. add 1 5. multiply by 250 6. add the last 4 digits of your phone number 7. add the last 4 digits (...)
hi what do you do with multiplier? this real question. in the communication for multiply the carrierand message the MC1496 is very low cost. but dynamic range is small. for high dynamic range the papular multiplier is AD633. that is low cost and can xproduce (XY+Z)/10 if ypu can specify your application (...)
For ur information Advance Encryption Standards (AES) has requirments as below: 1)Operates on fixed-length group of bits (block cipher) 2)Processes data as 4 groups 4 bytes(128 bits=>block size) 3)Symmetric key sizes(128,92 or 256 bits) 4)Has 9/11/13 rounds in which state undergoes(byte substitution,shift rows,mix coumns or (...)
An alternative to division is to multiply by a fraction.
