Lecture 8
What is PCI?
Peripheral Component Interconnect
Created by Intel in 1990
A local computer bus for attaching hardware devices
(ex. Network card, sound card, extra ports…)
Lecture 8
Hardware Specifications
33.33 MHz clock with synchronous transfers
Peak transfer rate of 133 MB/s for 32-bit bus width
32- or 64-bit memory address space
32-bit I/O port space
5-volt signaling
Lecture 8
Timeline
1992 PCI Intel
1996 AGP Intel
1998 PCI-X IBM, HP, Compaq
2004 PCI Express Intel, Dell, HP, IBM
Lecture 8
PCI Express
Developed by the PCI-SIG
A high-speed serial computer expansion bus
standard designed to replace the older PCI
higher maximum system bus throughput
Can have more power consumption than
conventional PCI

Lecture 8
PCI on Galileo (Mini PCIe)
based on PCI Express
Most laptop computers after 2005 adopt PCI Express
Intel® Galileo Board is the first Arduino board to
provide a mini PCI Express slot.

1.5 and 3.3 volt power
Lecture 8
Wi-Fi
In short, Wi-Fi is a technology that can make you
connect to Internet wirelessly.
The protocol,IEEE802.11, defined Wi-Fi’s MAC Layer
(ex. PCF,DCF…..) and Physical layer (ex. frequency,
modulation….) in 1997.
Has 5 generations until now

Other Application of Wifi
RTLS (Real-time locating system)
Combine RFID and WiFi together to provide accurate
location of objects.
Lecture 8
What is JTAG
Joint Test Action Group (JTAG)
IEEE 1149.1 Standard Test Access Port and
Boundary-Scan Architecture
4/5pins-TDI,TDO,TCK,TMS,TRST(optional)
Be used for IC debug ports
Useful for embedded systems development
Lecture 8
Source Level Debug on Galileo
Requirements
Linux host system
Quark-patched OpenOCD
GDB
Eclipse
Quark Kernel compiled with debug symbols

OpenOCD supported JTAG debugger
https://communities.intel.com/docs/DOC-22203
Lecture 8
What the debugger can do?
Remote debug the program on Galileo
Single-steping
Breakpoint
Show the location in the original code when the program
crashes
