Esmail Khois Rueckkehr nach Borgio Verezzi. [Esmail Khois' Return to Borgio Verezzi]
No full textEsmail Khoi’s poem Return to Borgio Verezzi (written in March 1983 and first published in 1984) belongs to the key texts of post-revolution Persian exile literature. Esmail Khoi is one of the leading voices of Persian poetry in the second half of the 20th century. His literary works since the beginning of his exile in London in 1982 include more than 20 books of poetry, translations of classical Persian literature (particularly the 14th century satirical poet Obey-e Zakani of Shiraz) into English and numerous articles and contributions to Iranian press in exile. Khoi was a founding member of the Iranian Writers’ Association and the Iranian PEN Center in exile. In 1989, after the annoncement of Ayatollah Khomeini’s fatwa (death sentence) against the British author Salman Rushdie, Khoi was among the founding members of the international committee for the defence of Salman Rushdie. Return to Borgio Verezzi is a long narrative poem which reflects many key aspects and features of Khoi’s work and personality as a modern poet with strong ties to the tradition of classical Persian poetry and as a politically and socially engaged exile. My paper consists of an introductory essay about the poem. Initially it uses the methodology of “explication de texte” with a text immanent approach. In the further development of the essay the historical and intertextual references to the poetry of Hafis, Forugh Farrokhzad and Nasser-e Khosro are also discussed. The essay is followed by my translation of the poem into German. The booklet is accompanied by an audio CD with an original recoding of Esmail Khoi reading his poem in Persian. Literary critics generally consider Esmail Khoi as one of the best voices to recite poetry by himself and also by other classical and modern Persian poets
A multiprocessor self-reconfigurable jpeg2000 encoder
No full textThis paper presents a multiprocessor architecture prototype on a field programmable gate arrays (FPGA) with support for hardware and software multithreading. Thanks to partial dynamic reconfiguration, this system can, at run time, spawn both software and hardware threads, sharing not only the general purpose soft-cores present in the architecture but also area on the FPGA. While on a standard single processor architecture the partial dynamic reconfiguration requires the processor to stop working to instantiate the hardware threads, the proposed solution hides most of the reconfiguration latency through the parallel execution of software threads. We validate our framework on a JPEG 2000 encoder, showing how threads are spawned, executed and joined independently of their hardware or software nature. We also show results confirming that, by using the proposed approach, we are able to hide the reconfiguration time
Hardware DWT accelerator for MultiProcessor System On-Chip on FPGA
No full textHigh performance multimedia applications are typical targets of today embedded systems. These applications, complex both in terms of execution flow and amount of elaborated data, can be well addressed by multiprocessor systems on-chip (MPSoCs). MPSoCs are composed of simple processors and memories tightly interconnected with fast communication channels and customized IP cores for the most demanding functions can be implemented and attached to these systems to enhance performance even more. Reconfigurable devices like FPGA, can act as a target, even programmed at runtime, for the custom IP cores, or as a prototyping platform for the whole system. Image compression like JPEG2000, can benefit very much from this approach and this type of architectures. This paper shows how the most demanding task of the JPEG2000 compression algorithm, the two-dimensional discrete wavelet transform, can be hardware accelerated and implemented in a multiprocessor system-on-chip prototyping platform on field programmable gate array (FPGA), CerberO. Architectures with different number of processors and hardware accelerators, shared among the processors or dedicated, have been implemented. To validate the approach, we show some experimental results on the platform with the hardware and the software implementation of the transformatio
Pequeños vertebrados del relleno kárstico del Pleistoceno Superior de Avetrana (Apulia, Sur de Italia)
No full textThe fossiliferous deposit (karst cavity) in La Grave, a locality near the small town of Avetrana (Taranto, southern Italy), has yielded numerous fossils of vertebrates. The remains of large mammals have been the subject of several studies. This paper examines the remains of small vertebrates and identifies four taxa of amphibians (Bufo bufo, Bufotes gr. B. viridis, Hyla gr. H. Arborea and Rana (s.l.) sp.), four taxa of reptiles (Testudo hermanni, Podarcis sp., Zamenis gr. Z. longissimus, Natrix natrix), and nine taxa of small mammals (Erinaceus europaeus, Crocidura suaveolens, Arvicola italicus, Microtus (Terricola) savii, Microtus (Microtus) arvalis, Apodemus gr. A. sylvaticus - A. flavicollis, Hystrix (Acanthion) vinogradovi, Oryctolagus cuniculus and Lepus corsicanus). From a biochronological point of view, the data on small and large vertebrates indicate an age between the beginning of the Late Pleistocene (MIS 5e) and the central part of MIS 3. The most recent fossiliferous layer (bed 8) is likely to have been deposited during a cooler period when compared to the previous layers.The data from small fossil vertebrates combined with those emerging from the large mammals and birds evidence the presence, near the karstic cavity, of open spaces (prairies) with pools of water, bordered by wooded areas and, not far, the presence of a rocky coastline.El depósito (cavidad kárstica) de La Grave, localidad cercana a la pequeña ciudad de Avetrana (Tarento, Italia meridional), ha dado lugar a numerosos fósiles de vertebrados. Los restos de grandes mamíferos han sido objeto de varios estudios. En este trabajo se examinan los restos de pequeños vertebrados y se identifican cuatro taxones de anfibios (Bufo bufo, Bufotes gr. B. viridis, Hyla gr. H. Arborea and Rana (s.l.) sp.), cuatro de reptiles (Testudo hermanni, Podarcis sp., Zamenis gr. Z. longissimus, Natrix natrix), y nueve de pequeños mamíferos (Erinaceus europaeus, Crocidura suaveolens, Arvicola italicus, Microtus (Terricola) savii, Microtus (Microtus) arvalis, Apodemus gr. A. sylvaticus - A. flavicollis, Hystrix (Acanthion) vinogradovi, Oryctolagus cuniculus and Lepus corsicanus). Desde un punto de vista biocronológico, los datos sobre los vertebrados pequeños y grandes indican una edad entre el comienzo del Pleistoceno tardío (MIS 5e) y la parte central del MIS 3. Es probable que el estrato fosilífero más reciente (nivel 8) se haya depositado durante un período más frío en comparación con las capas anteriores. Los datos de pequeños vertebrados fósiles combinados con los que proceden de los grandes mamíferos y aves evidencian la presencia, cerca de la cavidad kárstica, de espacios abiertos (praderas) con charcos de agua, bordeados por zonas boscosas y, no muy lejos, la presencia de una costa rocosa
