90 DSP48 units of this FPGA are enough to implement a lot of DSP algorithms.But you would rather implement the filters and FFT in the sequential-parallel manner.When...

Re: Processing Gain at output of ADC

Reply posted 5 months ago (06/05/2020)
Really, gain is 5 bits. But in conditions when the signal has not the DC component. If you needn't such a gain you can truncate the resulting bit width to the desired...

Re: How to make sure clock is from the main clock tree?

The synthesis tool usually doesn't need the clock frequency at all. But one of the synthesis result is the maximum frequency which provides this design. It is estimated...

The RTL design paradigm insists that any device must have a clock signal wire and all registers are feeded by it writing the information by the clock edge.So, any...

Video stream compressor.At present, many old compression method patents are expired,and these methods may be freely implemented in FPGA.Consider GIF.

Re: Pink noise generator on FPGA

Reply posted 2 years ago (12/07/2018)
Usually, the pink noise is derived from the white noise by the filtering.Build the white noise generator based on LSFR, and attach to its output some band pass...

Re: A Law compression for FPGA

Reply posted 2 years ago (08/23/2018)
A-law is an algorithm of the log compression of the audio signals.It attracts for its simplicity. But it works bad for other data compression.You need other kind...

Re: Reduce Phase of a filtered data set

Reply posted 3 years ago (08/16/2017)
There is a special kind of filters called the minimum phase filters.They have unlinear phase characteristic but their group delay is minimized. For example, if a...

Re: Overloading assignment operator '<=' in vhdl

Reply posted 3 years ago (05/15/2017)
the operator '<=' is overloaded for any type of the signal.But the left and right sides must be of the equal type or be subtype of this type.You can assign the...

Re: DSP Filter Verification in FPGA

The up conversion filter is calculating the input sequence, which is split by zeros. Therefore, the output results are divided by 2 if the conversion is made up...

Re: manipulation of two dimensional matrices in VHDL

Reply posted 4 years ago (10/13/2016)
In such a situation, I usually use something like perl script to generate the vhdl text with the matrix content. (Perl can be built in the simulator). But in modelling,...

Re: Glitch on Articx7

Reply posted 4 years ago (10/07/2016)
A "glitch" is a product of a bad design. Therefore, it would not be afforded during "translate, map and place and route ". If a real glitch is buried in the...
