Hi all, Please provide me some valuable inputs regarding multiplier using shift and add method in verilog. say : multiplicand and multiplier be two inputs of 8 and 6 bits respectively. (...)
Here is my code for shift and add multiplier (datapath controller method) Can anyone please see the code and see where I'm going wrong. It just doesn't seem to work. The datapath is like this Datapath. However I've c
hi is there any body who khnow the circuit of below?: i want this for logic circuits lab : i want to make a multiplier with "shift & sum alghoritm",for example with shift register and etc...,if any body khnows,how can i make this , tell me immediately,plz i will be thankful
Hi, i have learned the shift register code in VHDL as the following: if (reset = '1') then shift <= '0000" ; else if (clock' event and (clock= '1')) then shift <= shift (2 downto 0) & si; can anyone tell me this is shift left or shift right? because (...)
Hi, What are the bit shift and rotate instructions used in visual Basic (like << or >> operators in C Language) ? Thanx in advance
Dear Forum Members, Why We Use Copper Pour In The Circuit, and How To add It In Orcad?
what is the difference between arithmetic shift and logical shift? What is the advantage and disadvantage concerned to both? Does anybody know?
Hi all, How >>(right shift) and <<(left shift) 2'complement number (both positive and negative integer). Is x>>2 equal to floor(x/4)? and is x<<2 equal to x*4? Best regards, Davy
hi all, I want to see know how shift and hold registers are loaded with values in EDT mode. When i open in the design i am seeing the values in the first shift register is the result of edt_update and edt_channel input. But in the reference guide it is given the masking bits will be (...)
Why we are using various frequency for Functional mode and shift mode??? whether physical design engineer have a mandatory work to MET the setup and hold time in both mode?????

hi all, i want some clarification about tech file given with the software. -- normally what i have seen that we refer λ as scalable parameter for sizing and generally use 2λ = X micron . but for o.5 micron tech file they wrote that λ = 0.30 micron for this process SCN3M_SUBM. -- whats the difference between SCN3M_SUBM (...)
I use UT-CPC6264-70LL I don't know how to read and write,and how to see the data in 6264 by MEDWIN. For read,I just need to MOVX A,@DPTR?

I think MSP430 from TI is exactly what you need. They are prety cheap and some versions have a hardware 16x16->32 multiply/accumulate unit (as a memory-mapped peripheral).
Hi I need to shift the whole band into baseband. To do so, we multiply by e^-2*pi*f(c). Can you please show me how to implement this in VHDL and Verilog?
You can just use the built in VHDL multiply operator, *. The synthesizer can convert this to the appropriate multiplier.

In a normal receiver frequency offset can be detected and compensated by AFC(Automated Frequency Controller). If Doppler frequency shift exists, can this frequency offset be detected by AFC in the same way? Or we have to do something special to cancel Doppler effect?
Hi folks, Any relationship between phase/gain/bandwidth and jitter? I am designing a limiting amplifier using acticve inductive peaking configuration. I found everything else is ok but jitter. I thought this mightbe because of too much phase shift (1.5G, about 180 degree) due to (...)
hi, can any one give me the reason of phase shift and calculation of phase shift. thanx.
