Resource consumption of Heterogeneous block elements

Dear Friends,

I am currently doing my PG project in area minimisation of IP core(Router, Processing Elements and Filter etc) blocks.

For this i need reference of various heterogeneous block elements area/resource consumption interms of LE's. Since i am taking worked out reference of LE's

Is there any link or document which gives comparison of LEs and Heterogeneous block elements power consumption, bandwidth, delay..etc details?

Regards,

Deena
