 * Understanding of the operation of a moderately complex digital system; a simple RISC-based computer we called the $$\beta$$ using the building blocks above, and ability to specify, implement and **debug** its components.
 * Exploration of both **hardware** and **software** mechanisms through a series of design examples (labs and 1D/2DC projects)

-> *The computer lies at the heart of computing. Without it most of the computing disciplines today would be a branch of theoretical mathematics. To be a professional in any field of computing today, one should not regard the computer as just a black box that executes programs by magic. All students of computing should acquire some understanding and appreciation of a computer system’s functional components, their characteristics, their performance, and their interactions.There are practical implications as well. Students need to understand computer architecture in order to structure a program so that it runs more efficiently on a real machine. In selecting a system to use, they should be able to understand the tradeoff among various components, such as CPU clock speed vs. memory size.*

+> *The term **architecture** is taken to include instruction set architecture (the programmer’s abstraction of a computer), organization or microarchitecture (the internal implementation of a computer at the register and functional unit level), and system architecture (the organization of the computer at the cache and bus level). Students should also understand the **complex trade-offs** between CPU clock speed, cache size, bus organization, number of core proces- sors, and so on. Computer architecture also underpins other areas of the computing curriculum such as operating systems (input/ output, memory technology) and high-level languages (pointers, parameter passing).*
