Regarding p4080 instruction opcode details.

[Simbu]

Hi et al,

I'm working on a project in which we are trying to port one operating system into p4080 for which curently studying the existing powerpc (970mp) card registers and instructions against p4080 R&I set.but couldn't able to find micro level details in p4080 reference/user manuals like hex type opcode for all instructions/changed instructions.Below are my outstanding question's:

- Document (if any)/Link which will give view on register and instuction set change/diffrenence between old power pc family.

- Document/Link which will give view on instruction opcode like below:

In PPC970 for addi (X3800 0000),I need document which wil help me to get Hex code for all instruction.

Thanks a bunch in Advance..

The PPC family is documented in lots of different books.If you've ever used a chip with an ARM core in it you'll have the same problem. The book for the chip refers to the ARM documentaiton, and there's no end of that.

Read the following for previous examples of trying to find the book that tells you what you want to know:

Another problem with the PPC is that most of the instructions you'll find in assembly source "don't exist" and aren't listed in the section of the manuals (PEM) that list the instructions. They're listed in "Appendix F - Simplified Mnemonics" of the PEM and there's 24 PAGES of them.
