6.3.8. The DDR3 Tab

This tab allows you to read and write DDR3 memory on your board.

Figure 29. The DDR3 Tab

The following sections describe the controls on the DDR3 tab.

Start

Initiates DDR3 memory transaction performance analysis.

Stop

Terminates transaction performance analysis.

Performance Indicators

These controls display current transaction performance analysis information collected since you last clicked Start:
  • Write, Read and Total performance bars: Shows the percentage of maximum theoretical data rate that the requested transactions are able to achieve.
  • Write (MBps), Read(MBps) and Total(MBps): Show the number of bytes of data analyzed per second.
  • Data Bus: 72 bits (8 bits ECC) wide and frequency is 1066 MHz double data rate. 2133 Mbps per pin. Equating to a theoretical maximum bandwidth of 136512 Mbps or 17064 MBps.

Error Control

This control displays data errors detected during analysis and allows you to insert errors:
  • Detected errors: Displays the number of data errors detected in the hardware.
  • Inserted errors: Displays the number of errors inserted into the transaction stream.
  • Insert: Inserts a one-word error into the transaction stream each time you click the button. Insert Error is only enabled during transaction performance analysis.
  • Clear: Resets the Detected errors and Inserted errors counters to zeroes.

Number of Addresses to Write and Read

Determines the number of addresses to use in each iteration of reads and writes.
