Well, this is my first demo (in fact is a remix of various codes AWEHAUWheUAHW). It shows a matrix multiplication with hardware (sh4 ftrv instruction) and software (made with adds and muls WAHEUhaWUEH).
It uses the kos mat_load (load a matrix into the xmtrx registers), mat_apply (multiply xmtrx with another matrix) and mat_store (load a matrix from xmtrx to a variable) functions.
I´ve noted that all the matrix´s has to be transposed, and the result is transposed too, or something like that AWJEIjaWIjeAIje.
NOTE: AWEHUAHWEUahU is a laugh in brazillian.

EDIT: this isn´t compiled, so you need the toolchain (i use the dcdevr3).
