Took a look at some papers on this and it's a pretty interesting parallel implementation of multiplication. Though looking at it I can't understand how a barrel shifter would be used to implement it. About the only way I can envision using a barrel shifter is if the implementation is done as an FSM algorithm with a single multiplier, so you rotate
I do not. However I can tell you that a straight single gate device drawn with w=16000u is just stupid and would not ever be done (you want a 1.6cm die in one dimension?). So step back, assign a stripes / multiplier and a sane w value. If you can't do it that way then parallel N sane- geometry FET instances.
What is the natural form of your operands? A voltage, or a current? Simplicity argues for using the multiplier form that requires the least translation (which always adds something you don't want, and costs you something you do). A current mirror is simpler than a voltage buffer, and you can do addition with current sources in parallel much eas
The "multiplicity" parameter m (or M) is the shunt multiplicity factor of an instance, that is, the number of identical devices that are combined in parallel - see any HSPICE manual. You can't use it for an array.
Your problem has more to do with poor architecture, you've implemented 100s of constants in FFs. Then you use those 100s of FF constants in 150 multiplier instances (all in parallel). Given the way you've coded this you are trying to implement something with 150 multiply accumulates in a single clock cycle. Are you really sure this is what you want
Hello, I am working on a project that requires a very lightweight circuit for harvesting power from a button-cell battery (cr2032 or similar). My circuit requires about 12v but the cell is only 3v. Since only pulse operation is needed (12v is required at a fraction of time, every a vew seconds), I am thinking ofslowly charge some capacitors in pa
If You have multiplier option You can use it to make parallel connection of N mosfets or use vector by naming the instance like T0 to make parallel connection of N+1 identical fets.
M is the 'multiplier'. M=10 would mean 10 identical transistors in parallel. Keith
I think you might be able to do this with a parallel controlled current source (multiplier), "sniff" the inductor current and add a variable (perhaps use a ccvs -> vmult -> vccs) parallel current. Macromodel style?
Firstly, look at signal graphs, they both represent the DSP algorithm and can be equal to the DSP unit structure, i.e. addition, multiplication, delay nodes are mapped to adder, multiplier, register respectively. Secondly, Power electronics is rather slow to be controlled by FPGA, where the parallel algorithms are usually implemented. It would
Hi All, I need "Verilog HDL code for a 32-bit Braun multiplier". plz anyone help me to implement an "16 bit unsigned parallel Braun multiplier" using Verilog HDL code... also I have not so much knowledge of Braun multiplier.. So my dear friends if u have any study materials about Braun multiplier, (...)
Hi nice guys I am a beginner of layout. how to layout very wide mosfet in cadence automaticaly? I konw I can use multiplier to set the parallel of the mosfets. e.g. I set the multiplier 500, then how can I connect the drains and sources of these mosfets? Can connceted automatic? otherwise I need connect the the drains and sources (...)
how to multiply 8 bit data using parallel multiplier....... plz atleast tel the algorithm which is used........
what is the difference between a serial and a parallel multiplier? i need to build a VHDL code for 12 bit parallel multiplier in radix 4 booth algorithm i want to build the digital system such that it uses a clk... can somebody help me?
Hey, could anyone provide me some sample solution of Parametrizable parallel multiplier?thanks! draw a picture of 4X4 block multiplier. Especially find out how the carry and sum signals are connected between blocks. Tasks: * Create the 1-bit multiplier element. It is recommended to create it as a component to (...)
Hi, I want to implement parallel chien search algorithm on FPGA.I found some material in which there are two methods are shown to implement the parallel chien search algorithm. In one method there are pt different g.f(2) multiplier(a^1,a^2,a^3,a^4....a^pt) are used. while in other method there are only t multiplier are (...)
to build qpsk use divide and conquer divide the system into: 1-serial to parallel converter 2-mapper: map every 2 bits to corresponding i,q 3- sin,cos oscillator 4- multiplier 5- adder not that hard
in serial-parallel adder and if u r giving me then give of 8 bit
Hi guys If I have one 16-bit multiplier, can I use it as 2 separate 8-bit multipliers (probably running in parallel) ? .. is there any multiplication algorithm / multiplier architecture that supports that ?
parallel divider cores included with major vendors tools can be expected to be fastest to my opinion. Usually, they have additional parameters to control pipelining and optimization. In contrast to looking out for the fastest, I often have the need to use a slower but more economic serial divider.
