in assembly in order to take advantage of the 386's 32-bit capabilities.
There's another area of the program that fairly cries out for assembly
language: matrix math. The function to multiply a matrix by a vector
(**XformVec()**) and the function to concatenate matrices
(**ConcatXforms()**) both loop heavily around calls to **FixedMul();** a
(`XformVec()`) and the function to concatenate matrices
(`ConcatXforms()`) both loop heavily around calls to **FixedMul();** a
lot of calling and looping can be eliminated by converting these
functions to pure assembly language.
Listing 53.1 is the module FIXED.ASM from this chapter's iteration of
X-Sharp, with **XformVec()** and **ConcatXforms()** implemented in
X-Sharp, with `XformVec()` and `ConcatXforms()` implemented in
assembly language. The code is heavily optimized, to the extent of
completely unrolling the loops via macros so that looping is eliminated
altogether. FIXED.ASM is highly effective; the time taken for matrix
