  1. Hello there, I have developed a fixed point design, then an IP core for matrix multiplication using vivado HLS.I need to deal with fixed point data types in Vivado SDK to send data to a fixed point IP core.Does anyone has any idea of how can i go about.?Thank you
  2. HI there, I have a zed board. Developing a design in HLS for algorithmic acceleration. When I run the c-simulation for my design in HLS , it is not run showing the following error: But when i do c-synthesis it synthesizes the design with synthesis report, where in under latency and interval I see question marks: '?' why this happens and how do i understand this behavior? How can i get it corrected? Thaks in advance
  3. Hello there, This time i have a very simple design in HLS which takes in a 3d matrix, multiplies with a constant and gives output. It works for [64][64][64] matrix perfectly, but not for [128][128][128] matrix. Again I get the segmentation fault. Can somebody help me to know what fundamentally going wrong.. Thanks for your halp in advance. i have attached my design files here: core.cpp core.h core_test.cpp
  4. Hi there I just want to verify how to store float values in DDR3 of zed board. I have written a small code, but when i read from memory, i am not getting the correct answer. Is it correct? can someone help me? #include <stdio.h> #include "platform.h" #include "xil_printf.h" #include "xil_io.h" #include "xparameters.h" #define DDR_BASEADDR 0x01000000 int main() { init_platform(); int i; float img[5] = {11.2345 ,17.2135 ,11.65 ,18.543 ,7.6789}; for (i = 0; i <5; i++) { Xil_Out32(DDR_BASEADDR+(i*4),img); } cleanup_platform(); return 0; }
