Name of the exercise

VMEbus data transfer

Responsible for the exercise

Markus Joos

Description of the exercise

The students will write a C program that executed VMEbus single cycles and block transfers to write data to a VME memory and to read it back.

What will the students learn

• Writing a simple C program to exchange data with a VMEbus module
• Understand and use an existing VMEbus library
• Compare the relative speed of different VMEbus transfer modes

Duration

2 hours. Time permitting the students can refine the program in the free time to go deeper into S/W performance profiling

List of material

H/W:

• 1 VMEbus crate
• 1 CCT SBC
• 1 VMEbus D32/MBLT memory module
• 1 VMEbus display module

S/W:

• Linux file system and gcc compiler / linker
• vme_rcc, cmem_rcc and io_rcc driver
• TDAQ RCD S/W (vme_rcc and related libraries)

Relevant Information
