H1	Lattice Mico32 FPGA embedded processor

Implementing and programming a processor core in an FPGA

Goals Understand the process of creating a system with an FPGA-embedded processor Assembling the hardware platform Installation of FPGA Programming of application software Final Integration Master the particulars of the Open Source MICO32 core: Software architecture Wishbone bus Standard peripherals: UART, Ethernet (10/100/1000) ... Learn to program a the platform using Eclipse. Discover installing uClinux and micrium uC/OSII on the platform This course teachs you how to control the creation of a platform using an embedded CPU. All exercises are done on a board with the Lattice ECP2 Open Source MICO32 core; installation and use of Micrium uC/OSII and uClinux will be presented quickly.

Course Material A Windows PC per two trainees The Lattice Diamond FPGA programming tool The MSB tool for creating Mico32 Open Source platform The software development environment (based on Eclipse) The installation of the platform on uClinux and uC/OSII A Lattice ECP2 target board Printed handouts of the course slides Labs presentation and solutions

Prerequisite Basic understanding of processor architecture Good knowledge of VHDL programming (V1 - VHDL Language Basics course level) Knowledge of embedded programming in C (if possible L2 - C language for Embedded MCUs course level) For a good understanding of installing uClinux it is desirable to have a basic knowledge of Embedded Linux (see D1 - Embedded Linux with Buildroot and Yocto course) to understand the uClinux boot process Linux programming (see D0 - Linux user mode programming course) for Linux programming exercises
