The NMNS AXIe-0 module is a mezzanine module carrier made in the AXIe-0 standard. The module provides the functioning of the various modules installed in it, made in the form of mezzanines. The NMNS AXIe-0 module is intended for use as a mezzanine carrier in multichannel systems for collecting / issuing information of both digital and analog form.

The main function of NMNS AXIe-0 is to accumulate a large amount of information in the form of binary codes coming from mezzanines at high input frequencies and a large number of channels when it is not possible to process data in real time.

In the mode of issuing information on mezzanines, NMNS AXIe-0 provides the output of data recorded in its internal memory at specified intervals in a single time grid to specified mezzanines.

The NMNS AXIe-0 module performs batch buffering of data from dissimilar mezzanines with data binding to a single time grid and provides access to the current (received at the last moment of time) measurement results on any channel.

NMNS AXIe-0 is used as a part of information measuring systems based on the AXIe-0 trunk and is installed in the AXIe 0 standard chassis on the seats of tool modules.

Number of installed mezzanines
up to 4
Launch of mezzanine functioning modes
  • programmatically
  • on a programmatically selected signal (any of 12) of the trigger signal bus coming from the AXIe trunk (external start mode);
  • by the “Start NM” signal from the mezzanine (asynchronous operation mode)
Mezzanine sharing interface
  • management interface - serves to configure and control the state of the mezzanine;
  • data interface - is used to read mezzanine measurement results in RAM and output data arrays from RAM to output mezzanines
Management Interface Features
  • the number of bits of the control bus - 16 bit;
  • the number of bits of the address bus - 5 bit;
  • recording cycle duration - from 160 to 187 ns;
  • minimum reading cycle time 160 ns
Methods for controlling the processes of exchange with mezzanines
  • control the sequence of arrival of words from the mezzanine;
  • control by DATA_VALID and EMPTY signals
Device sharing modes with mezzanines
  • synchronous
  • asynchronous
The ability to read current data with timestamps at any time without interrupting the process of the device
Yes
The presence of memory type SDRAM
Yes
