Why is a sum statement so bizarrely synthesized?
I have 4 buttons on an FPGA dev board so I wrote
function [HEX0] = Bar(KEY)
n = uint8(sum(KEY, 'native'));
...
Unfortunately, HDL Coder turned it into the following chunk of VHDL:
y := '0';
FOR k IN 0 TO 3 LOOP
y := y OR KEY(k);
END…

How do I implement matlab code on hardware device to make it run?
My question is quite basic to most appropriate levels on consideration. I lack the perception of how can I dump or implement my matlab code on a hardware component like processors or fpga? For eg:
Suppose I create an image processing matlab (object…

how to optimize (reduce) the latency in the verilog HDL code (hardware) generated by the MATLAB HDL CODER add-on from a given Simulink model?
Thanks in advance,
I am having a simple Simulink model, that takes in a 32-bit number in the IEEE-754 format and adds the same number, which gives the output again in the 32-bit wide IEEE-754 format. I used MATLAB's HDL CODER add-on and generated…
