eCACTI is a tool used for finding an estimate of cache area, access times, and power dissipation for a given set of parameters (cache size, block size, associativity, and technology).

eCACTI is an enhanced version of an existing tool, CACTI, that was developed by Wilton and Jouppi.

The main enhancements in eCACTI are:

Estimation of leakage power dissipation

Calculation of device widths as a function of capacitive loads

Calculation of power dissipation in all cache sub-blocks

The technical report on eCACTI is available in ps or pdf.
