Telemetry Card & Modular Interface Products

Model 1622AP High Performance PCI Single Board Data System

Acroamatics’ Model 1622AP delivers new higher rate processing speeds and new capabilities, yet retains 100% “drop-in” compatibility with existing Acroamatics PCI TDP family products. We’ve utilized the latest in PGA component technology to ensure both low power consumption and improved reliability – ensuring integrators and end-users trouble-free, upgrade into friendly performance well into the next decade.

We’ve added lots of new features to the new 1622AP, including those that enable users and integrators to easily exchange data and set-up files with legacy Acroamatics TDP systems and card sets, to add list based display and storage events, to easily record and regenerate PCM streams, along with IADS Server, IRIG Chapter 9 TMATS, Lab Windows, and ILIAD instrumentation analysis and display software support.
Most importantly, the new 1622AP retains Acroamatics signature card level, real-time stored program processing technology. All 1622AP TM processing tasks are performed within its card level processors maintaining a 100% Windows independent and deterministic telemetry decommutation environment.

The compact 1622AP provides both main frame and six software programmable “soft decom” driven sub-frame decommutators – each with multiple onboard data and conditional stored memory program locations, The Model 1622AP is designed to support transparent use of standard Windows driven PCI bus and system peripherals in support of data recording, data display and networked data distribution – making it both an extremely reliable as well as a very effective all-in-one telemetry processing solution.

Mainframe Sync
Mainframe synchronization 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 subframes 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 4022 CTS PCI card level real-time user input format switching. Format 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.

Standalone Data Output
Data is processed in specialized card resident real-time processors, independent of any Windows (or similar) operating system. Processing latency is minimal, and related solely to access to rate parameter data. Decommutated data are available to the system internal PCI bus as memory-mapped frame buffers. Current Valule Table (CVT), or as a data stream selectively 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 complete suite of GUI Windows compatible system set-up and operating programs in support of user decom and mission system data management, data display, alarming, limit setting, recording, analog and networked data I/O processes and local operator status display, and networked remote system management and data operations.
