Question about JIT
« on: September 04, 2003, 03:33:01 PM »
JIT, "Just In Time", the conversion of instructions from 680x0 instructions to a combination of PPC RISC instrutions that achieve the same thing in the CPU.

Can this be done, a 680x0 program, be run through a RISC JIT, and then that combination of commands be saved back to disk as a new file. Then just run that "RISCed" program, from then on? Could this be done to a BASIC program?

On one end its CISC command A, then it gets converted to RISC command B (C, (D)), just save it then to disk and build the new program. It would have to examine the branches as well.

So I guess that A500, 600, 1000, 2000, CDTV, CD32, are pure garbage then? Thanks for posting here.

Are you refering to source code you have?


For instance Power Packer, the source might not be available, so the JIT converts every instruction to PPC then runs it. I thought the JIT could be used to run the program, command by command, but instead of running, it saves the resulting commands into a file. Effectively converting it into a PPC program.


A1!
