Thus, the composition of the host language and user-selected extensions can safely be performed by someone with no expertise in language design and implementation. The analysis is necessarily conservative and imposes some restrictions on the grammar. We argue that the analysis is practical and the ...
Evaluating attribute grammars (AGs) is an extremely memory space consuming problem. Optimizing the memory space management procedures is therefore an highly rewarding challenge. We consider this problem for evaluators of the simple multi-visit class, also calledl-ordered, because it is the largest pos...

part of the attribute grammar. The semantic part is managed by a special purpose module that traverses the parse tree as many times as needed, in order to evaluate the attributes. The entire system is described in Verilog HDL (Hardware Design Language), ...
The entire system is described in Verilog HDL (hardware design language), in a template form that given the specification of an arbitrary attribute grammar, the HDL synthesizable source code of the system is produced on the fly by a proposed automated tool. The generated code has been simulated...
This implies that the compiler produced automatically on the basis of the grammar uses space in the same way as a practical hand-written recursive descent compiler. Furthermore, a graphical notation is introduced as a design tool for obtaining grammars in the proposed class....
AGENDA: an attribute grammar driven environment for the designautomation of digital systemsAttribute grammars have been used extensively in every phase of\ntraditional compiler construction. Recently, it has been shown that they\ncan also be effectively adopted to handle scheduling algorithms in\nhigh-...
A template in attribute grammar is an abstraction of a semantic rule parameterized with attribute occurrences. On the other hand, the whole attribute grammar is a subject of multiple inheritance and specialization. With the proposed approach, a language designer has the chance to design incrementally...
attribute grammar transformation, which increases the incremental performance of the attribute evaluators after a change that propagates its effects to all parts of the syntax tree. These techniques have been implemented in a purely functional attribute grammar system and the first experimental results ...
In this paper, these past results are further elaborated and integrated in the construction of a prototype for an attribute grammar driven hardware compiler from behavioral descriptions to VHDL. Due to its flexibility and rapid design, such a compiler can be used as a workbench for testing ...
