SYSTEMS APPLICATIONS

Most Intel486 processor systems can be grouped as one of these types:
• Embedded Personal Computer
• Embedded Controller
Each type of system has distinct design goals and constraints, as described in the following sec-
tions. Software running on the processor, even in stand-alone embedded applications, should use
a standard operating system such as DOS*, Windows 95*, Windows NT*, OS/2*, or UNIX Sys-
tem V/386*, to facilitate debugging, documentation, and transportability.
