| - | * Abstract: As the number of system gates available on reconfigurable platforms increase beyond 20 million, the issue of the management of these resources and their sharing among may applications and users will become more of a concern. In this paper we describe the research issues for managing these resources in an operating system for a reconfigurable computer. We also detail a feasible set of components for the operating system and a feasible software architecture We show there is no current operating system implementation with these components. We propose a number of performance metrics which we believe are important measures of the quality of an operating system implementation. These include fragmentation of area, algorithm performance and application performance. We complete the paper with a status report on our implementation of an operating system for a reconfigurable computer. | + | |

| - | * Abstract: Reconfigurable computing applications have traditionally had the exclusive use of the field programmable gate array, primarily because the logic densities of the available devices have been relatively similar in size compared to the application. But with the modern FPGA expanding beyond 10 million system gates, and through the use of dynamic reconfiguration, it has become feasible for several applications to share a single high density device. However, developing applications that share a device is difficult as the current design flow assumes the exclusive use of the FPGA resources. As a consequence, the designer must ensure that resources have been allocated for all possible combinations of loaded applications at design time. If the sequence of application loading and unloading is not known in advance, all resource allocation cannot be performed at design time because the availability of resources changes dynamically. In this paper, we present an implementation of an operating system that has the ability to share its FPGA resources dynamically among multiple executing applications. | + | |

| - | ** Description: Witam wszystkich, przesyłam dość ciekawy artykuł opisujący zadania systemu operacyjnego w dynamicznie rekonfigurowalnym FPGA (zarządzanie dostępem do pamięci, virtual adressing, dynamiczna alokacja itp). Chociaż zaprezentowane rozwiązania są bardzo ogólne, to uważam, że warto ten artykuł przeczytać. | + | |

| - | ** Description: Podazajac tropem Piotrka natrafilem na ciakawy artykul (w zalaczniku) prezentujacy opracowany w Berkeley system operacyjny (rozszerzenie UINX'a) dla architektur opartych o FPGA. Artykul jest dosc "swiezy" bo z 2006 roku. Co wiecej, w Transactions on Embedded Computing Systems 2008 znalazlem artykul tych samych autorow, o tym samym tytule (niestety, nie udalo mi sie dotrzec do jego tresci). Zasadnicza czesc proponowanego systemu pracuje na procesorze PowerPC znajdujacym sie w glownym FPGA. Oprocz glownego FPGA sa jeszcze 4 uklady "user FPGA", w ktorych realizowane sa zadania uzytkownika. Osiagnieciem autorow jest ujednolicenie obslugi zadan implementowanych sprzetowo i programowo. Choc glowna koncepcja przedstawiona w artykule znacznie rozni sie od naszego pomyslu to warto go przeczytac ze wzgledu na prezentowane w nim mechanizmy komunikacji miedzy zadaniami i dostepu do pamieci. Lekture polecam szczegolnie naszym informatykom. Jak widac z artykulu, odpowiednia architektura sprzetu moze znacznie przyspieszyc prace systemu operacyjnego. Mocna strona artykulu jest to, ze nie przedstawia on jedynie luznych koncepcji ale konkretne, sprawdzone rozwiazania. | + | |

| - | ** Description: Po krotce mowiac, praca dotyczy opracowania narzedzi i metodologii (COMMA design flow opartej na Early Access Partial Reconfiguration Tool Flow) wspierajacych synteze ukladow wykorzystujacych modulowa rekonfiguracje dynamiczna na wspoczesne uklady rekonfigurowalne XILINX'a (rodzina Spartan-4) i jednoczesnie wspolpracujace z dostepnymi narzedziami producenta. Glowny nacisk w pracy polozony zostal na generacje i optymalizacje polaczen pomiedzy modulami dynamicznie rekonfigurowalnymi. Zaproponowane podejscie umozliwia zachowanie takich paramterow projektu jak np. ograniczenia czasowe, przy jednoczesnym spadku czasu dynamicznej rekonfiguracji do okolo 64% (w porownaniu do zastosowania dostepnych komercyjnie narzedzi). Autor w pracy implementuje model Brebnera ("fixed wiring harness" model), a tazke algorytm greedy'ego do łączenia grafow wsparte, rozwiniete czy tez nawet zastapione przez metode dynamicznego programowania. | + | |

| - | ** Description: The tree SSA project requires a tree representation of functions for the optimizers to operate on. There was an existing functions-as-trees representation shared by the C and C++ front ends, and another used by the Java front end, but neither was adequate for use in optimization. In this paper, we will discuss the design of GENERIC, the new language-independent tree representation, and GIMPLE, the reduced subset used during optimization. | + | |
