We undertook the characterization of an actin gene and its proximal promoter in the oyster Crassostrea gigas. A complete actin cDNA was identified, sequenced and its amino acid sequence deduced. Comparative analysis showed a high homology with actin of other species and that this gene is closer to the cytoplasmic form of actins than to the muscle type. A(More)
High-level synthesis (HLS) allows hardware to be directly produced from behavioral description in C/C++, thus accelerating the design process. Loop pipelining is a key transformation of HLS, as it improves the throughput of the design at the price of a small hardware overhead. However, for small loops, its use often results in a poor hardware utilization(More)
Research on High-Level Synthesis has mainly focused on applications with statically determinable characteristics and current tools often perform poorly in presence of data-dependent memory accesses. The reason is that they rely on conservative static scheduling strategies, which lead to inefficient implementations. In this work, we propose to address this(More)
Loop pipelining is a key transformation in highlevel synthesis tools as it helps maximizing both computational throughput and hardware utilization. Nevertheless, it somewhat looses its efficiency when dealing with small trip-count inner loops, as the pipeline latency overhead quickly limits its efficiency. Even if it is possible to overcome this limitation(More)
GeCoS is an open source framework that provide a highly productive environment for hardware design. GeCoS primarily targets custom hardware design using High Level Synthesis, distinguishing itself from classical compiler infrastructures. Compiling for custom hardware makes use of domain specific semantics that are not considered by general purpose(More)
Magainins are peptide antibiotics with broad antibacterial and antiparasitic activities, originally extracted from the skin of Xenopus laevis. We investigated the effects of magainin 1 against Bonamia ostreae, the intrahemocytic parasite of the flat oyster Ostrea edulis. Viability of purified protozoa was assessed microscopically by the uptake of the vital(More)
