IMHO, a really good place to start for that is:

David Gudeman, "Representing Type Information in Dynamically
Typed Languages" [TR 93-27, Department of Computer Science,
University of Arizona, Tucson, AZ (October 1993)]
This report is a discussion of various techniques for representing
type information in dynamically typed languages, as implemented
on general-purpose machines (and costs are discussed in terms of
modern RISC machines). It is intended to make readily available a
large body of knowledge that currently has to be absorbed piecemeal
from the literature or re-invented by each language implementer...
