- VHDL Examples EE 595 EDA / ASIC Design Lab. Example 1 Odd Parity Generator- This module has two inputs, one output and one process.- The clock input and the input.
- Description CKT Diagram VHDL Model Typical logic circuit entity myckt is Port ( A,B,C,D: in stdlogic; F: out stdlogic); end myckt; architecture ckt1 of myckt.
- Implementing image processing algorithms in VHDL is a scary thing for many. Though I agree that its much more difficult to do it in VHDL than in a high level programming language like C, Matlab etc, it needn't be that scary. In this post I am going to share the code for a simple image processing algorithm - A RGB to Gray scale image converter.
