Comtech AHA Corp.


Experience and expertise are driving Comtech AHA Corporation's groundbreaking achievements in communications technology. AHA is a fabless semiconductor company that develops, markets, and licenses data coding technologies such as Reed-Solomon, Turbo Product Codes, Low Density Parity Check Codes, and lossless data compression for the communications, networking, and data storage markets. Since 1988, AHA has been developing and distributing integrated circuits (ICs).
 
With a history rich in innovation, AHA is a company of firsts in FEC technology, including production of the first single-chip Reed-Solomon IC and the first commercially available Turbo Product Code hardware. AHA was also the first to develop Content Addressable Memory architectures for high-performance single-chip data compression. AHA's current product lines of FEC and Lossless Data Compression products are based on these patented technologies. Comtech AHA Corporation is a wholly owned subsidiary of Comtech Telecommunications Corporation (NASDAQ:CMTL).




Product Name: AHA3602C
Product Category: Documentation Tools - ASIC and IC Design

The AHA3602C GZIP compression core a high-speed hardware compression accelerator available for ASIC and FPGA implementations. It is fully compliant with the GZIP File Format Specification version 4.3 (RFC-1952), the ZLIB Compressed Data Format Specification version 3.3 (RFC-1950), and the Deflate Compressed Format Specification Version 1.3 (RFC-1951). The core can generate compressed files and individual deflate blocks.

Product Name: AHA3610
Product Category: Documentation Tools - ASIC and IC Design

The AHA3610 GZIP compression coprocessor is a single chip CMOS VLSI device that implements the open-source GZIP (Deflate) lossless data compression and decompression algorithm. It supports a simultaneous compression/decompression data rate of 2.5 Gbits/sec, while achieving compression performance equivalent to GZIP S/W. The device implements 2 high speed 16-bit parallel DDR interfaces for easy integration in to many microprocessor based systems.

Product Name: AHA370PCIe
Product Category: Documentation Tools - ASIC and IC Design

The AHA370PCIe is a PCI Express plug-in card that adds GZIP compression acceleration to data networking systems.  This card supports data rates of 10.0 Gigabits per second while achieving high compression ratios equivalent to high effort GZIP software.  Communication and storage networks require high speed compression solutions to reduce latency on communication links, reduce bandwidth on these links, and reduce media requirements when storing files to disk or tape.

Product Name: AHA400PCIe
Product Category: Documentation Tools - ASIC and IC Design

The AHA400PCIe is a PCI Express plug-in card that recovers lost packets in a network. The board encodes and sends FEC source packets and repair packets through the channel. A matching decoder on the receiving end will recover lost packets. The maximum channel coded block size is 255 packets. Depending on channel conditions, not all of the repair packets need to be transmitted. When the decoder at the receiving end has received 128 packets out of the total 255 source and repair packets for that specific block then the original 128 source packets are restored and output over the PCB’s DMA interface.

Product Name: AHA4702D
Product Category: Debugging - Structured/Platform ASICs

DVB-S2 Compliant LDPC/BCH Forward Error Correction (FEC) Decoder Core

The AHA4702D FEC decoder core is fully compliant with section 5.3 of the Digital Video Broadcast S2 (DVB-S2) standard.  It is capable of 200 Mbit/sec user data rate with a 2/3 rate LDPC Code and 25 iterations in an ASIC.  The core supports all codes, frame sizes, and interleave schemes set forth in the DVB-S2 specification for broadcast, interactive, digital satellite news gathering, and professional services.  The core allows code and modulation changes on a block-by-block basis to fully support both Adaptive Coding and Modulation (ACM) and Variable Coding and Modulation (VCM).
