In the previous post, I introduced my idea of implementing the Mandelbrot set on an FPGA and described the Mandelbrot set equation and the Escape-time coloring algorithm. This post will talk about the implementation. Modeling the Mandelbrot set I consider it a good idea to start any FPGA implementation work with some planning, and in the case of an algorithm, the first thing you’d want to do is write a simple implementation of it…
Introduction to the Mandelbrot set Like I mentioned in the previous post, I wanted to familiarize myself with the HDMI output on the DE10-nano FPGA board, and there is no harm in getting some pretty graphics along the way, so I decided to implement a Mandelbrot set viewer on FPGA. If you are not familiar with the Mandelbrot set, it is a type of a fractal, which is simply put an infinitely – repeating recursive…
I know there wasn’t much updates on the minimig status, but with good (;)) reason: I’ve been pretty busy, so I had little time to work on minimig updates. I did spend quite some time on rewriting the CPU <-> minimig interface, which will hopefully reduce timing problems and enable me to finally add the ethernet Zorro interface. The CPU clock will also be reduced to 28MHz, hopefully that won’t affect the CPU speed much. This is quite…
QMEM bus specification This post describes the QMEM bus, the different cycles allowed, the bus elements and different bus configurations supported. 1. Introduction 2. Features 3. Signals Description 4. Cycles Description 5. Bus Elements 6. Bus Configurations Introduction QMEM (abbreviated from quick memory), is a flexible, portable, simple and fast system interconnect bus, specifically targeted at SoC systems for their inter-chip communication needs. QMEM is based on synchronous memory bus with added flow control signals,…
