EPspectra: a formal toolkit for developing DSP software applications
نویسندگان
چکیده
The software approach to developing Digital Signal Processing (DSP) applications brings some great features such as flexibility, re-usability of resources and easy upgrading of applications. However, it requires long and tedious tests and verification phases because of the increasing complexity of the software. This implies the need of a software programming environment capable of putting together DSP modules and providing facilities to debug, verify and validate the code. The objective of the work is to provide such facilities as simulation and verification for developing DSP software applications. This led us to develop an extension toolkit, EPspectra, built upon Pspectra, one of the first toolkits available to design basic software radio applications on standard PC workstations. In this paper, we first present EPspectra, an Esterel-based extension of Pspectra that makes the design and implementation of portable DSP applications easier. It allows drastic reduction of testing and verification time while requiring relatively little expertise in formal verification methods. Second, we demonstrate the use of EPspectra, taking as an example the radio interface part of a GSM base station. We also present the verification procedures for the three safety properties of the implementation programs which have complex control-paths. These have to obey strict scheduling rules. In addition, EPspectra achieves the verification of the targeted application since the same model is used for the executable code generation and for the formal verification.

متن کاملDeveloping Reliable yet Flexible Software through If-Then Model Transformation Rules
Developing reliable yet flexible software is a hard problem. Although modeling methods enjoy a lot of advantages, the exclusive use of just one of them, in many cases, may not guarantee the development of reliable and flexible software. Formal modeling methods ensure reliability because they use a rigorous approach to software development. However, lack of knowledge and high cost practically fo...

Synthesis of digital signal processing (DSP) software from dataflowbased formal models is an effective approach for tackling the complexity of modern DSP applications. In this paper, an efficient method is proposed for applying subroutine call instantiation of module functionality when synthesizing embedded software from a dataflow specification. The technique is based on a novel recursive deco...
متن کاملUltra-Low-Energy DSP Processor Design for Many-Core Parallel Applications
Background and Objectives: Digital signal processors are widely used in energy constrained applications in which battery lifetime is a critical concern. Accordingly, designing ultra-low-energy processors is a major concern. In this work and in the first step, we propose a sub-threshold DSP processor. Methods: As our baseline architecture, we use a modified version of an existing ultra-low-power...
