4. Forth > Hardware

Hardware

How should people see the hardware they develop on: as a resource or as a limit? If you think of hardware as a resource, you might want to optimize the code and exploit every hardware feature; if you see it as a limit, you are probably going to write code with the idea that your code will run better on a new and more powerful version of the hardware, and that’s not a problem because hardware evolves rapidly.

Chuck: A very perceptive observation that software necessarily targets its hardware. Software for the PC certainly anticipates faster computers and can afford to be sloppy.

But for embedded systems, the software expects the system to be stable for the life of the project. And not a lot of software is migrated from one project to another. So here the hardware is a constraint, though not a limit. Whereas, for PCs, hardware is resource that will grow.
