Power Scaling Library (PSL)

 Package 5,1,0 Release Notes

Last updated: 10 Nov 2004

This release note covers general product level issues and is divided into four sections, "General Info", "Fixed In This Release", "Known Issues", and "Validation Info".     

 

General Information

The Power Scaling Library (PSL) is a software library that allows embedded systems programmers to manage both frequency and voltage scaling through an easy to use API. The PSL provides hardware abstraction, portability, and a standard API that can be used among different TI devices. The result is shortened development time for the end user.  Included in the API are routines that initiate scaling operations, and various query routines that provide information on current settings and available frequency/voltage settings.  Frequency changes are initiated directly by the user. Voltage changes are performed indirectly by the PSL when a frequency change occurs.  Specifically, the PSL will automatically scale the voltage to the minimum level required by a frequency.  Since voltage changes are only initiated indirectly, the PSL can ensure a legal frequency/voltage setting at all times.
