Software analysis led to the conclusion that the limit is caused by the resolution of the single-precision floating-point
format used by a 32-bit device and software.
Today's FPGAs incorporate hardened digital signal processing (DSP) blocks are capable of implementing efficient 27-bit x 27-bit multipliers that provide extra bits above the normal single-precision 24-bit mantissa requirement for single-precision floating-point
Assuming peak rates for both systems, you can see that the PS3 is highly unbalanced and favors single-precision floating-point
In addition, MATLAB 7 offers built-in support for integer and single-precision floating-point
math, as well as language features for managing and analyzing larger data sets.
The resolution will not, however, affect how the data is stored because the single-precision floating-point
data type will accommodate either 12- or 16-bit data.
Except for IEEE denormals, this allows single-precision floating-point
values to be used directly in double-precision arithmetic and branches.
