MXI Interfaces To Everything—a custom ASIC designed by National
Instruments that implements the PCI bus interface. The MITE supports bus
mastering for high speed data transfers over the PCI bus.
Peripheral Component Interconnect—a high-performance expansion bus
architecture originally developed by Intel to replace ISA and EISA. It is
achieving widespread acceptance as a standard for PCs and workstations;
it offers a theoretical maximum transfer rate of 132 Mbytes/s.
