Weighted Average Calculation of SSO
This section describes the SSO calculation where the SSO contributions of all I/O in a bank
are combined into a single figure.
SSO of an individual bank is calculated by summing the SSO contributions of the
individual I/O standards in the bank. The SSO contribution is the percentage of full
utilization of any one I/O standard in any one bank. For drivers of each I/O standard, the
calculation follows:
For a bank with drivers of multiple I/O standards, the SSO calculation is:
A sample SSO calculation follows. The system parameters used are:
First, SSO limits for each I/O standard are obtained from
The SSO contribution of each I/O standard is calculated as:
Finally, the bank SSO is calculated:
Bank 1 SSO = SSO contribution (1) + SSO contribution (2) + SSO Contribution (3)
I/O Group
SSO Contribution (I/ O group n) = (quantity of drivers)/(Bank SSO limit)
