there are some 'lookup table' models in the simulink , and i want to use some model to deposit datas and renew these datas, can the 'lookup table' model achieve my target? or some other models can achieve? and could yuo give me a model tell me hou to use it to achieve my target? thank you

..........I need a help regarding standard cell Library format for decoder. there are some std cell lib format for adder,clk etc but i could not findout the lib format for decoder... did the select lines for example s0 s1 also been tabulated in the lookup table along with the input pins.
..........And in adder should the two output

You can use Excel to generate part numbers, create bills of material and cost them including quantity price breaks using lookup tables and generate purchase orders.
You can use conditional formatting to automatically change cell colours according to different constraints. All of this kind of approach is covered in my book (plus lots more)

You will need to create font lookup tables for all the characters you wish to display. You then use the ASCII code representing each letter of words you wish to display as a lookup in the font table. The best is to break your code into sections such as getting fonts, sending to display, and the scrolling part which is the easiest ... simply move th

I am using the ee214 lecture notes for studying. I found that Prof.Murmann has additional notes provided like gm/ID, gm.Cgg lookup tables. I need those to understand his lectures. There are mentioned in pg.240 of his notes.

a resistive(two pin small in size like switch pad on pcd ) humidity sensor i am using. i need lookup table for this sensor
If it is resistive, then you will be measuring the voltage and this voltage will be linear. Without the data sheet it will difficult to provide a LUT.

Are you using a Xilinx device? Which one?
Try the "DDS Compiler" or "Direct Digital Synthesizer" cores included with Xilinx ISE CORE Generator.
Or build your own DDS. Feed a frequency constant into an ordinary arithmetic accumulator. Connect the accumulator output to the address inputs of a sinewave lookup table ROM. The ROM output is your di

Can anybody tell me how to estimate the power consumption in synopsys .lib file?
What's the Unit, uW/MHz?
eg: 0.18um inverter
If i use C×Vdd?×f to calculate the dynamic power, then 0.00200pF loading matches the result (0.00200p×1.8?×1MHz = 0.00648uW, which is less than 0.008075 in the table).
but 0.396000pF loading will lead to 1.28304uW/MHz

If your device has spare block RAMs available, try using a lookup table.
The two least-significant bits can bypass the table.

Hey everyone.... I have yet another pic question..... I need to know if their is a way to look up 'text' strings that exceed the page boundary? any examples in assembly would be helpfull.... thanks all!

This sort of thing is often done with a lookup table. You precompute the answers for the desired range of inputs and then pre-load them into a BlockRam within the FPGA.

I have researched about the topic in books and on web. I believe I have learnt more, but l still need some help to clarify the concept:
CPU is a processor that execute instructions defined by a particular ISA.
FPGA is a programmable processor, that can implement any digital functions/procedures.
Is it true to draw the conclusion that: FPG

DDFS : is based on lookup table or ROM and a phase interploator to scan the lookup table and get the digital words crosponding to the sinewave , and then these words passed to DAC and filter
the frequency resolution is very high and the switching speed is very high , but consumes alot of power specially the DAC
the all didital PLL is a PLL b
