Chapter 1 Introduction
block transfer rates by integrating the MITE custom ASIC, a sophisticated
dual-channel DMA controller with standard interfaces for VXI, VME,
MXI, PCI, and PXI. By using MITE DMA to transfer data and commands
to and from devices, the MITE frees up a computer's microprocessor to
perform other tasks such as data analysis and presentation. In addition to
DMA, the MITE incorporates both the new Synchronous MXI protocol and
VME64 MBLT (8-byte block transfers in which both the address bus and
data bus are used to transfer data) directly into the ASIC to perform the
fastest transfers to instruments.
