architecture within the Digital Equipment Corporation.” Id.
at ll. 61-66. The RISC architecture is “embodied in equipment
made by Digital Equipment Corporation ....” Id. at ll. 66-68.
Indirect migration involves compiling and linking the
higher-level source code “by means of an X compiler 16 and an
X linker 18.” Col. 6, ll. 16-17. The compiling and linking
produce “X executable code 14 which can run on the X computer
system 12.” Id. at ll. 18-19. The X executable machine code
is architecture-dependent. Specifically, the X executable
machine code “can be a RISC instruction set. For example, as
specifically indicated for illustrative purposes in FIG. 1,
the X
system can employ the VAX® architecture ....” Col. 5, ll. 59-
63. The RISC architectures is “embodied in equipment made by
Digital Equipment Corporation ....” Id. at ll. 66-68.
Following, compiling and linking, the X executable machine
code is translated “into the corresponding Y executable
