Portable stream programming language (PSPL) is a language for baseband application programming on reconfigurable architectures. The first step in its development has been completed. A parser has been provided for the front end of the PSPL compiler. The syntax of the language has been fixed to allow for easy parses. The scanner and the parser where generated using automatic tools (scanner and parser generators) which rely on complex mathematical algorithms for their generation. Abstract syntax (data structures that preserve the source program so that program structure is evident) was implemented for the parser using a syntax separate from interpretation style of programming. Tests were carried out to ensure that the correct data structures were generated. The final outcome is a parser that other phases of the compiler can depend on for onward transmission of the source program in an unambiguous manner. The development of subsequent phases of the...
