Learn compilers with online courses and programs

A compiler functions as a translator, converting human-written, high-level source code into machine code, enabling the computer to execute the program. Learn about compilers with online courses delivered through edX.

What are compilers?

Compilers translate code from one programming language to another, converting high-level code into a format the CPU can interpret. This involves parsing the source code into elements such as keywords and variables, ensuring it adheres to the language's syntax rules. Any errors prompt notifications to the programmer. After syntax validation, the compiler ensures logical consistency before generating the final machine or assembly code for execution.

Various compilers offer different features. Cross-compilers work on one operating system but target another. Decompilers revert low-level code to high-level, while bootstrap compilers are written in their target language. Source-to-source compilers transition from one code to another without altering abstraction level. A compiler's core tasks include lexical analysis, preprocessing, parsing, and semantic analysis, crucial for precise code transformation.

Compiler course curriculum

Compilers serve as essential tools that transform human-readable code into machine-executable instructions, facilitating efficient and accurate software execution on computers. The realm of compiler technology integrates various disciplines such as language theory, semantics, syntax, computer architecture, and data structures/algorithms.

An introductory compiler course typically delves into the mechanics of translating a program from a high-level language, tailored for human understanding, into one written in low-level assembly, which is inherently machine-centric. Such courses often encompass instruction on building programming language compilers, executing syntax-directed translation, performing dataflow analysis, and generating code. Students will likely engage with intricate processes like constructing abstract syntax trees and understanding runtime systems. As the curriculum progresses, one might explore the intricacies of programming language design, delve deeper into programming language semantics, and discuss the reasons behind the multitude of existing programming languages.

Learning about how to use this tool can supplement your knowledge of computer science. edX offers a variety of educational opportunities for learners interested in studying these topics, as well as a host of other disciplines. A boot camp can provide flexible hands-on learning for those who want to upskill quickly, while executive education courses are designed for busy professionals. You can also pursue a more comprehensive curriculum in a bachelor’s degree program or, for more advanced learners, a master’s degree program. Find the right learning path for you.
