[tremor] Tremor on DSP

[timmy brolin]

You are trying to implement the integer  ogg tremor on a floating point DSP??? Why?
Use the original floating point ogg vorbis.

Hello all,

I'm trying to implement a 64-bit type on a DSP that doesn't have a
native 64-bit integer type implemented, but does have a 64-bit floating
point type.

Is there a complete list of all the operators that I need to implement
for this 64-bit integer type, aside from the basic +, -, /, and * ?

Thanks

Kapil

Hi,

This is actually a project for University.
So you would have to be enrolled in our program to participate. =)

But thanks for your interest.
