Re-configurable I/O interfaces for modern Data Acquisition Systems
نویسندگان
چکیده
A modern approach to high speed I/O interfacing is proposed through the use of a flexible architecture based upon Field Programmable Gate Arrays (FPGA) and the PCI bus. Three distinct solutions are reviewed, all manufactured according to PMC (PCI Mezzanine Card) standard: one solution is CPU-based and the other two are CPU-less. The reconfigurability of the architectures is emphasized, showing that, by means of modern design techniques, one can easily partition between hardware and software some CPUdemanding or high latency tasks that are typical of modern Data Acquisition Systems. keywords I/O interfaces, FPGA, vxWorks, PMC

A Network Interface Card Architecture for I/O Virtualization in Embedded Systems
In this paper we present an architectural concept for network interface cards (NIC) targeting embedded systems and supporting I/O virtualization. Current solutions for high performance computing do not sufficiently address embedded system requirements i.e., guarantee real-time constraints and differentiated service levels as well as only utilize limited HW resources. The central ideas of our wo...

In contemporary research, “Heterostructure” assemblies play an important role in energy conversion systems, wherein the composite assemblies facilitate faster charge carrier transport across the material interfaces. The improved/enhanced efficiency metrics in these systems (electro/photo-electrochemical processes/devices) is due to synergistic interaction and synchronized charge transport a...
متن کاملStandardized But Flexible I/O for Self-Virtualizing Devices
Moving device virtualization from the virtual machine monitor (VMM) to the devices improves virtual-machine performance significantly, but it requires support from the devices. PCI and PCI Express (PCIe) devices can provide VMs with direct and secure I/O through the use of multiple functions per card, but at significant cost and inflexibility. One solution to help reduce the costs is the PCIe S...
