Overview

Strata is a framework for doing software dynamic translation research. 

Strata operates in coroutine with the application, dynamically examining each instruction of the application before it is allowed to execute.

 

 

Strata is:

  • Low overhead - it uses its fragment cache to amortize the cost of translating the application.
  • Flexible - Strata is implemented on x86, Sparc, and MIPS, and able to be easily extended.
  • The basis for numerous tools in security, optimization, and profiling. 
  • Available by contacting one of the project members.
