News for

Midterm PDF and ZIP package posted.

Lecture video 9 posted.

Added links to the FIR and IIR Python filter design tools description used in ECE 4680 labs 4 and 5, respectively, to supplement notes Chapters 6 and 7.

Assignment #4 and associated ZIP posted. More parts will be added to the assignment.

ZIP package for Assignment 3 now posted. Maybe repost the Jupyter notebook a few more comments later this week.

The address to the Keil license server has changed. See the lower right column.

An alternative to the Analog Discovery is Soundcard Scope. You may need to get an external sound card interface such as AFUNTA or similar. Only has mono mic input. A line input is available in the iMic and USBGear.

To get going with Python see the right column where I provide a link to Anaconda, a good scientific Python install.

Background Requirements

I hope that each student/student team will purchase the Cypress $50 kit. I have a few loaner kits get the class started in lab on the first day of class. The syllabus contains many more links.

The required background for all students taking the course is an introductory graduate or junior/senior level undergraduate course in DSP and experience programming ANSI C. We will be making use of the ARM CMSIS-DSP library library for sure. The Yui text contains two DSP oriented chapters. If you need a C/C++ refresh consider the C/C++ Programmers Reference.

Obtaining Mathematica

Mathematica is available across the campus due to the CU system wide site license. This system-site license also means that students may install their own copy on home computers as well. Some links of interest regarding the CU site license for Mathematica are: download and installation and support information.

The Keil License Server

In short under the File menu, then License Management, then Flex LM, enter the server address as: 27000@LM-AGILENT.UCCS.EDU. You may have to run Keil as a Admin from startup. You need to use the campus resources VPN when connecting from off campus.

To help you get started with the Keil integrated development environment (IDE), here is the mdk5-getting started document.

Catalog Course Description

An introduction into the design, development, and implementation of signal processing alogithms on real-time hardware targets. The emphasis will be on high-level language (e.g., C), but assembly language will also be discussed.
Prerequisite: ECE 5650/4650, or ECE 2610/3205 or equivalent
Offered: Spring

Problem Sets - C6x


This course is about the use of general purpose digital signal processing microprocessors for solving signal processing problems in real-time. The new version of the course with utilize the ARM Cortex M4 processor family. Previously the course focus was on using the Texas Instruments (TI) C6x family of fixed and floating processors, and in particular implementing programs written in assembly, linear assembly, and C for the OMAP L138 (C6748 DSP). The old material is still available on the Web Site with the tag - C6x.

For both processor families the course will start out considering general signal processing applications of real-time DSP. A focus applications area will be communication system design using DSP algorithms. The course meeting time will be used for lecturing and laboratory time using Cortex M4 (old C6x) hardware/software development tools ARM Keil at first (old Code Composer Studio).
