CSE430/830 Course Project Tutorial

Instructor: Dr. Hong Jiang

TA: Dongyuan Zhan

Project Duration: 01/26/11 – 04/29/11

Objectives

• Get familiar with the fundamental ideas of computer architecture

• Finish a semester-long project: building a pipelined 32-bit RISC processor with

– HW-based data hazard resolution mechanisms

– a static branch predictor

– instruction/data caches

– assembler & bubble-sort application

• Practice efficient teamwork that makes your work splendid.

Teams

• Since there are exactly 30 students, each team is required to have 3 (or 4) members

• A team would better have a member who has taken CSE230 and its Lab

• Each team is required to have a team leader who coordinates the group’s project events

• Each team needs to maintain a project wiki to update the group’s progress


Tasks

• Task 1: determine the ISA– tailor the ISA that is targeted at the bubble-sort

application– write the bubble-sort program and compile it with your

own designed assembler

• Task 2: pipeline the processor– add pipeline stage registers– add HW-based data hazard resolution mechanisms

• Task 3: add a static branch predictor– move the branch decision and branch address calculation to

the “instruction decode” stage– “always-not-taken ” is the easiest– performance counters are required to monitor the prediction

accuracy


Tasks

• Task 4: incorporate instruction/data caches– both are directly mapped– #(sets), block size, write policy are critical design

parameters– performance counters are required to monitor the hit

rates of the caches

• Project Wiki– a log of weekly meeting– the high-level/architectural view of your design– the verification of the correctness & efficiency of

individual components and the entire system– a summary of the work that you have done and that

lags behind

Software

• How to use Quartus-II IDE– very detailed tutorials are in “$PATH\Project

Documents\DE2_System_v1.6\DE2_tutorials\”

– some important memos:

» open an existing project by double clicking a “*.qpf” file

» specify the FPGA when creating a project• Cyclone-II EP2C35F672C6

» connect the inputs and outputs of your design to FPGA’s pins in Quartus-IIAssignmentPins

» download an “*.sof” file to DE2 via Quartus-IIToolsProgrammer


Software


» differentiate functional and timing simulations in Quartus-IIAssigmentSettingsSimulation SettingsSimulation Mode

• How to utilize the USB-to-Serial communication– Prerequisites

» install Putty & the USB-to-Serial driver

» download “uart_example.sof” to DE2

– Steps

» connect DE2 to a laptop with a USB-to-Serial cable

» in “Device ManagerPort(COM & LPT)”, check out the COM number, which may change when you connect to a different USB port on your laptop

Software


Software


check the “serial” box

specify the “serial line” with the COM #

specify the “Speed” to be 115200

specify the “flow control” to be “None”

click “Open”

Software


The Hyperterminal used to demonstrate

the uart-to-usb communication content

Suggestions for a Good Project

• Carry out efficient teamwork

• Plan well and make steady progress

• Keep project wiki well-organized

• Use version control system, such as SVN, to manage your source code

• Deploy effective and efficient debugging strategy

• Be active in discussing with the TA
