Setup

Network Cable

Target- Demo application

Host- CCS- Web Browser

Multi-core Software Demonstration

• SYS/BIOS-MCSDK provides tested and supported components like:• SYS/BIOS – real time optimized

OS for scheduling• Platform Development Kit (PDK)

– application interface to C667x peripherals like network coprocessor

• Inter Processor Communication – mechanism to communicate across cores

• Image Processing Demonstration provides• Use of TI’s image processing

library• Starting point for image

processing product development

Image Processing

• Connect PC and board• Set PC network configuration• Launch target configuration• Load program and run• Viewing result via PC web browser

Connect PC and board

• Connect the board to PC using Ethernet cable. • Connect XDS100v1 and power on board.

Set PC network configuration

• The demo runs in Static IP mode ;board IP address 192.168.2.100,Gateway IP address 192.168.2.101 and subnet mask 255.255.254.0

• Set up PC TCP/IP configuration of ‘Wired Network Connection’ like below:(start->network connections->Wired Network Connection->Internet protocol(TCP/IP) )

Launch target configuration

• Switch to target configuration window• Right-click on c6678_XDS100v1_emu.ccxml,

select ‘launch selected configuration’

Connect target

• Group all cores

• Select group 1; right click ,then select ‘connect target’

Load program and run

• There are two images to be loaded to master (core 0) and other cores.

• Select core 0, load program<MCSDK INSTALL DIR>\demos\image_processing\evmc667xl\master\Release \image_processing_evmc667xl_master.out

• other cores (referred as slave cores) to be loaded with <MCSDK INSTALL DIR>\demos\image_processing\evmc667xl\

slave\Release\image_processing_evmc667xl_slave.out

• When all loaded, select group 1, run all cores together.

• In the CIO console window, the board should print IP address information like below:

MCSDK IMAGE PROCESSING DEMONSTRATIONQMSS successfully initialized CPPI successfully initialized PA successfully initialized EVM in StaticIP mode at 192.168.2.100Set IP address of PC to 192.168.2.101PASS successfully initialized Ethernet subsystem successfully initialized Ethernet eventId : 48 and vectId (Interrupt) : 7 Registration of the EMAC Successful, waiting for link up ..Network Added: If-1:192.168.2.100 Service Status: HTTP : Enabled : : 000

Viewing result via PC web browser

• Open a web browser in the PC. • Enter 192.168.2.100 in web page.

• Please follow the instructions in the web page to run the demo.

• Note that, sample BMP images are provided in <MCSDK INSTALL DIR>\demos\image_processing\images

Thanks!
