I Have a lot of questions.

[Urian]

Hello. I am new at this forums and I´m MAC OS X Programmer but my knowledge is fewer than a lot of persons of that forum that are programmers and graphists in more than 1 company.

This post is because I´ve a lot of questions.

1) When I´ve Seen the NEC chip that has 128 cores and the technical specifications of that chip I´ve Told to me that this Chip cannot be a CPU, this is not the why of the design and I believe that if Nintendo uses this processor for N5/GCN2 it will be a Physics Processor Unit and a coprocessor to the CPU.

¿Am I wrong?

Edit: The reason that I saw that is because the processor is designed for works that need a lot of physics.
2) ¿What is more important the number of ops that can do a CPU or the number of ops that the CPU need for do a standard instruction?

3) ¿The Work of the VU1 in PS2 is the same of the GTE in PSX or is totally different?

PD: Sorry if my english is bad, English isn´t my natural languaje.

You are right that it can't be used as a CPU, but I doubt it will show up on N5 either because it was meant for pixel processing...

2) What is more important the number of ops that can do a CPU or the number of ops that the CPU need for do a standard instruction?

Standard instructions.

3) The Work of the VU1 in PS2 is the same of the GTE in PSX or is totally different?

It is. Fixed geometry.

It is. Fixed geometry.

But VU1 is a totally accesible Processor inside of the VU1 it has their own set of registers and instructions and cannot be a Fixed Geometry solution because is full programable and accesible.

My question is simple.

¿GTE of PSX and PS2 of VU doing the same job?

¿GTE of PSX and PS2 of VU doing the same job?

they do the same function but VU1 IS more flexible. (in practice for various reasons it ends up processing geomtry and shunting it acreoss to the GS).
