3ECE 449 – Computer Design Lab Your TA – Thursday session Kamal Sayeed Office hours: Wednesday 7-9pm, Room 203

4ECE 449 – Computer Design Lab Lab meetings Time: Tuesday 4:30pm - 7:10pm Thursday 7:20pm - 10:00pm Venue: ST-II, Room 203 The first part of each meeting is reserved for a lecture given by the TA and the following hands-on session The second part of each meeting is reserved for the previous experiment demonstrations and the work on the new experiment

5ECE 449 – Computer Design Lab Course description This course provides practical experience in designing digital circuits using VHDL for design description and FPGA devices for final implementation. Students learn to write an RTL code suitable for logic synthesis. Students gain “hands on” experience in every step of the circuit development.

6ECE 449 – Computer Design Lab Design process (1) Design and implement a simple unit permitting to speed up encryption with RC5-similar cipher with fixed key set on 8031 microcontroller. Unlike in the experiment 5, this time your unit has to be able to perform an encryption algorithm by itself, executing 32 rounds….. Library IEEE; use ieee.std_logic_1164.all; use ieee.std_logic_unsigned.all; entity RC5_core is port( clock, reset, encr_decr: in std_logic; data_input: in std_logic_vector(31 downto 0); data_output: out std_logic_vector(31 downto 0); out_full: in std_logic; key_input: in std_logic_vector(31 downto 0); key_read: out std_logic; ); end AES_core; Specification (Lab Experiments) VHDL description (Your Source Files) Functional simulation Post-synthesis simulation Synthesis

7ECE 449 – Computer Design Lab Design process (2) Implementation Configuration Timing simulation On chip testing

8ECE 449 – Computer Design Lab Expectations Practical knowledge of digital system design using VHDL (ECE 331, ECE 332) Knowledge gained in the ECE 447 course on Single-Chip Microcomputers would be useful (particularly in the last experiment)
