Introduction Cebollita is an entire system and tools package for teaching Computer Architecture. It includes a C-like language (C--), a compiler, an assembler, a linker, a loader, a utility to format a raw disk, a primitive operating system and shell, a MIPS-like ISA, and a software simulation of a machine that implements the ISA. Students implement the ISA (preferrably using SMOK). Cebollita exposes them to the interactions among all these components. Each component is simple enough that it can be modified easily, allowing design tradeoffs to be experienced, rather than just discussed. A Recipe Cebollita means "small (green) onion" in Spanish. Real Mexican restaraunts will prepare them for you as follows: Fry them in oil on high heat until tender (doesn't take long). Sprinkle them with salt and fresh lime juice. Yum. Simple and good. Virtues we should all strive for. Credits & License Copyright (c) 2005.
