  Toom-Cook multiprecision multiplication is a well-known multiprecision
multiplication method, which can make use of multiprocessor systems. In this
paper the Toom-Cook complexity is derived, some explicit proofs of the
Toom-Cook interpolation method are given, the even-odd method for interpolation
is explained, and certain aspects of a 32-bit C++ and assembler implementation,
which is in development, are discussed. A performance graph of this
implementation is provided. The Toom-Cook method can also be used to
multithread other types of multiplication, which is demonstrated for 32-bit GMP
FFT multiplication.
