Partnership Takes Quadros Systems into South America; Agreement with Brazil's Pleiades establishes sales, development and customer support network.

HOUSTON, Texas -- Quadros Systems, Inc., a leading supplier of configurable and scaleable real-time operating systems (RTOS), announced they have signed on Pleiades Sistemas de Comunicacao Optico Digitais Ltda. as a sales and embedded development partner in Brazil. Under the agreement, Pleiades will provide pre- and post-sale technical support for all of Quadros Systems products and customers in Brazil. The Pleiades team will build on the customer base it already shares with Quadros as well as seeking out new opportunities through a combination of sales, field engineering and application support.

Created by industry and academic professionals, Pleiades has become one of the most important research and development companies within Brazil's large telecommunications industry. It offers a vast array of research and development services and embedded solutions in telecommunications fields such as ATM, frame relay, PDH/STM, SONET, optical network technologies (FTTH/FTTC, HDSL, ADSL, MDSL, SDSL, ISDN), VoIP, wireless access (Bluetooth, UMTS, GPRS), and telecommunications systems management over SNMP. The partnership provides an integrated software platform and engineering services for rapid application development in the target markets.

"Brazil is the largest economy in Latin America and boasts a growing telecommunications sector," observed Stephen Martin, Director of Marketing. "Pleiades' exceptional expertise as a systems integrator in telecommunications has enabled it to develop a solid customer base among the leading technology companies in Brazil. We are excited about combining their strong technical credentials with the RTXC family of embedded software solutions."

"Today's embedded developers are seeking integrated solutions backed by strong local support," noted Nelson Guimaraes Filho, CEO and President of Pleiades. "The RTXC product line has demonstrated strengths in the telecommunications space, particularly with the integration of streaming media into mobile devices. These products are well-suited for many of the projects that we're already developing. This, combined with their exceptionally strong integration with popular hardware platforms such as Blackfin(R) and ColdFire(R), gives the Pleiades team an edge in developing solutions for the communications sector."

The RTXC Quadros RTOS family features four highly scalable real-time operating systems, offering distinct performance advantages for each of the major processing models. RTXC/ss (single stack) utilizes a lightweight specialized executive to support high data rate and signal processing applications. RTXC/ms (multi-stack) is optimized for control processing using an event-driven, prioritized, preemptive scheduler. RTXC/dm (dual mode) marries RTXC/ms and RTXC/ss and is ideal for convergent processing applications which combine DSP/dataflow and RISC/control processing in a single-core architecture. Both RTXC/ms and RTXC/dm are brought together under RTXC/mp (multiprocessing) in various combinations to support multicore and multiprocessor implementations.
