1612ap-front-page-screens-and-cards-web

Acroamatics’ Model 1612AP card embedded telemetry decom and multi-function processing module features the highest data rate and processing speeds in the industry, yet retains 100% “drop-in” compatibility with legacy Acroamatics PCI TDP products and systems.

Utilizing the latest in FPGA component technology to deliver both low power (1/3 that of the preceding generation) and improved reliability, the new 1612AP features real-time card embedded stored program processing technology, providing multiple software program driven sub-frame decommutators – each with multiple onboard data and conditional stored memory program locations. Though the 1612AP PCI decom operates wholly independently of its host Windows chassis administrative OS, it is designed to allow use of standard Windows driven PCI bus and system processes to independently record data to disk, drive Windows display processes, and share data over network connections – making it a very effective stand alone all-in-one telemetry processing device.

As part of an integrated multi-stream / low latency real-time telemetry processing solution, up to eight independent 1612AP cards operate in conjunction (via dedicated 64-bit I-Bus) with Acroamatics companion 1615AP PCI PDSP module. The PDSP delivers 100% Windows application independent card level EU derived, and user defined processing and output data formatting capabilities.

SYNCHRONIZATION

Mainframe Sync
Provides for programmable sync pattern and mask, complement pattern recognition, and variable length frame decommutation. The pattern may be up to 64 bits in length.
Subframe Sync
Six independent synchronizers are capable of decommutating sub-frames within subframes. Subframes synchronize to fixed recycle patterns, complement frame sync patterns, and various ID patterns. Both recycle and ID patterns may be assembled from multiple word locations. Recycle patterns may be up to 32 bits long.
ID Sync
Two types of ID synchronization are supported: JAM patterns of arbitrary values, and incrementing or decrementing frame counters with limit checking. ID sync words may be up to 16 bits in length.
Sync Strategy
Programmable Search-Check-Lock sync strategy, bit error tolerance, and bit slip window provide reliable frame synchronization.
Asynchronous Formats
Subframe synchronizer may be programmed to decommutate embedded formats having unique frame sync patterns and format structures.
Format Switching
16 testable flags store the results of select input stream bit and word comparisons to control real-time format switching Frame Sync / Decom format switching is loss-less and immediate. Multiple card resident micro-coded decom processing programs are stored in local decom memory in support of such conditional format switching events.

Outputs

Standalone Data Output
Data is available to the host computers PCI bus as memory-mapped frame buffers, Current Value Table (CVT), or as a data stream selectably transferred by PCI bus DMA. Data is 32 bits with programmable MSB/LSB output word justification, sign extension, or zero insertion for LSB output. Acroamatics Telemetry System Software (ATSS) suite provides a host of Windows compatible (XP and Windows 7 compatible) which support user decom set-up, mission set-up management, and a host of real-time data display, alarming, recording, discrete/analog, and networked data I/O processes and local operator status display, and remote system management and data operations support.
I-Buss Data Output
When used in a system configured with a 1605P or new 1615AP PDSP PCI level advanced telemetry processing modules, the Model 1612AP uses a 64 bit parallel “I-bus” low latency inter-card connection that processes messages containing thirty two bits of data, twelve bits of fine time (microseconds), two bits of status, and 17 bits of data identification. I-bus data can be formatted in either MSB or LSB justified form. LS-justified data can also be sign extended. I-bus decom data is transmitted to the 1605P or new 1615AP PDSP card resident distribution & algorithmic data processor. The 1605P/1615AP is capable of from up merging data from any of up to eight 1612P cards in a system, to form the desired EU processing data and formatted data output products in support of real-time analog (DAC) output, raw or processed data recording, real-time display, and networked data communications processes. Decom and bit sync data quality status words are generated for downstream data validation, as well.
