MicroBlaze Configuration for an RTOS Part 3 – Cache Configuration

by

This article will look into details the cache configuration for the MicroBlaze that was skipped in part 2. Configuring the cache correctly is critical to the overall performance of a MicroBlaze system and can also take a considerable amount of FPGA resource, especially block RAM. When configuring the cache, the goal is to use the minimum cache size required to meet the application’s performance but no larger.

MicroBlaze Configuration for an RTOS Part 2 – Configuration Parameters

This article aims at helping developers and designers who must configure a MicroBlaze system. Especially early on in the development process where the final firmware is not available for benchmarking and tweaking. At these early steps it is often necessary to select a good approximation of the final configuration to have a good idea of the resource usage of the MicroBlaze.

BASEplatform Support for Express Logic’s X-WARE IoT PLATFORM

We announced a few weeks ago support for the Express Logic ThreadX RTOS as well as the X-WARE IoT PLATFORM™ within our very own BASEplatform™. This article goes over some of the advantages of using JBLopen’s BASEplatform Board Support Packages (BSPs) and drivers along with Express Logic’s solution. What Is the BASEplatform The BASEplatform is … Read more

Zynq-7000 Connectivity Using the uC/OS BSP

Close up view of the Digilent Zybo development board showing the Xilinx Zynq-7000 SoC.

In two previous articles, I have looked at using Micrium’s uC/OS RTOS on the Xilinx Zynq-7000. I only covered kernel and storage. This time, I will be exploring some connectivity options in combination with the Digilent Zybo. Namely, using Micrium’s USB device solution and HTTP server through the Zybo’s Ethernet port. This is also a perfect opportunity to try the new and improved release of Vivado 2017.1.

The plan is to use the Zybo on-board SD Card to hold the html files for the HTTP server. To make it more interesting, instead of just copying the files using a PC, I’ll turn the Zybo into a USB mass storage device to access the SD Card.

This is a continuation of the snickerdoodle adventure, following last week’s successful “hello world” , using Micrium’s µC/OS RTOS. In this series of articles, I’m exploring the capabilities of the snickerdoodle as a development platform for high performance real-time operating systems. This time, I will be running an embedded file system on the snickerdoodle module, enabling … Read more

snickerdoodle says Hello World!

What would make a better first post about embedded software than a hello world project on a brand-new development board. It’s the krtkl snickerdoodle I received with much excitement last week. The SoM is based on the Xilinx Zynq-7000 SoC along with storage and wifi on the SoM. In these next series of articles, I’m … Read more
