C PP Final Project The project of Programming Paradigms module consists of the development of a complete compiler for a (source) language that you may define yourself, as long as certain minimal criteria are met. The tar- get machine for compilation is a realistic, though non-existent processor called SPROCKELL, for which a hardware-level simulator is […]

In Praise of Computer Organization and Design: The Hardware/ Software Interface, Fifth Edition “Textbook selection is often a frustrating act of compromise—pedagogy, content coverage, quality of exposition, level of rigor, cost. Computer Organization and Design is the rare book that hits all the right notes across the board, without compromise. It is not only the
Question 8 (11 marks) In multi-version concurrency control, transactions are allocated a timestamp (their start-time) and tuples are tagged with additional fields that hold information about the timestamp of the transaction that last read/wrote the tuple. TS(T) = start time of transaction T WTS(X) = TS of last transaction that wrote X RTS(X) = TS
