This system deals with proofs of partial. Guards are requirements that are placed before a command in CSP, laying down restrictions before a program command can be executed. This paper presents a proof system for CSP, a language for Communicating.
Events and processes are strictly differentiated. An event might be described as x in a CSP equation, and a process might be described as Y.
In his book, Hoare detailed the difference between events (specific moments of objects) and processes (how those objects behave over their life). The programming language Go, for example, has native concurrency and CSP features.ĬSP breaks down processes that happen concurrently and interact with each other, using algebraic equations and logic to describe the interactions. CSP can be used to analyze software, computer systems, and some programming languages. He refined his theory in the 1980s and published a popular book on CSP that book, simply titled Communicating Sequential Processes, is still regarded as one of the leading authorities on this language. This communication is algebraic and logical.ĬSP was initially developed by Tony Hoare in 1978. Communicating sequential processes (CSP), developed by Tony Hoare, is a formal language that arose at a similar time to CCS. In CSP, concurrent systems communicate through passing messages: sequential processes are communicating between each other. Concurrency allows normal computer programs to run properly by executing different tasks during the same period of time, but these tasks are not dependent on (or parallel to) each other. CSP describes concurrent processes, which operate simultaneously in a system but are not parallel. Hoare Chapter 607 Accesses 91 Citations Abstract This paper suggests that input and output are basic primitives of programming and that parallel composition of communicating sequential processes is a fundamental program structuring method. Communicating sequential processes (CSP) is a language that uses math and logic to analyze communication between systems.
