So_ip_idt core can be used create a decision tree directly in hardware. It can create DTs with univarite, multivariate and non-linear tests.
Creating DTs directly in hardware results in the significant increase of DT inference speed, compared with the traditional software-based approach.

A highly configurable DVB-T demodulator core suitable for a wide-range of applications included test, measurement and broadcast montioring equipment.
The core provides the DVB-T(H) extensions which when combined with the superior performance offered by our inter-carrier-interferance cancellation algorithm make this core ideally suited for mobile environments

The CMS0021 Single-channel Cable Modulator encodes a transport stream for J83 or DVB-C.
The resulting QAM-symbols are filtered and up-converted for output to the radio interface as a single I/Q sample stream for translation to the final RF frequency.

The CMS0024 Multi-channel Cable Modulator encodes up to four separate transport streams for J83 or DVB-C.
The resulting QAM symbols are filtered and up-converted, each channel to its own frequency division multiplex (FDM) sub channel.
The IF channels are then combined output to the radio interface as a single I/Q sample stream for translation to the final RF frequency.

The CMS0022 DVB-C/J.83 Cable Demodulator is a 4th generation design that exploits the vendor’s experience of QAM and OFDM systems for broadband terrestrial, satellite and cable modems.
The core forms an integrated cable demodulator solution comprising of the Universal QAM Demodulator(CMS0006) and J.83abc/DVB-C Cable FEC Decoder(CMS0018) cores.

The CMS0018 J.83abc/DVB-C Cable FEC Decoder combines all of the channel coding and Forward Error Correction functions specified by DVB-C and by J83 – Annexes A B and C

The CMS0018 includes functions for QAM constellation slicing, trellis decoding, de-framing, de-scrambling, de-interleaving, and Reed-Solomon decoding.

The CMS0044 J.83abc/DVB-C Cable FEC Encoder combines all of the channel coding and Forward Error Correction functions specified by DVB-C and by J83 Annexes A B and C.
It is designed to interface to external modulators or advanced upconverting DACs such as the Analog Devices AD9789.

The CMS0035 DVB-Satellite Modulator is an integrated core featuring our DVB-S/-DSNG modulator (CMS0010) and DVB-S2/-S2X modulator (CMS0025) cores. The CMS0035 core provides all the functionality required to address the requirements of the ETSI forward-link satellite Standards EN 300 421 (DVB-S), EN 301 210 (DSNG), EN 302 307-1 (DVB-S2) and EN 302 307-2 (DVB S2X), with additional support for DVB-S2X VLSNR operation
The core can operate in a constant coding-and-modulation (CCM) mode for all Standards and in the enhanced variable-coding-and modulation (VCM) and adaptive-coding-and modulation (ACM) modes provided by DVB-S2 and DVB-S2X.

The CMS0010 DVB-S/-DSNG Modulator with integrated Reed-Solomon encoder has been designed specifically to address the requirements of the ETSI DVB-S forward-link satellite standard (EN 300 421), with further options available for compatibility with the ETSI DVB-DSNG digital satellite news gathering standard (EN 301 210).
The core provides all the necessary processing steps to modulate a single transport stream into a complex I/Q signal for input to a pair of DACs, or an interpolating DAC device such as the AD9857. Optionally, the output can be selected as an IF to supply a signal DAC.

The CMS0025 DVB-S2/S2X Modulator with integrated LDPC encoder has been designed specifically to address the requirements of the ETSI DVB-S2 forward-link satellite standard (EN 302 307), section-1 together with the section-2 extensions (DVB-S2X), with additional support for DVB-S2X VLSNR operation. The core can operate in CCM and VCM/ACM modes.
The core provides all the necessary processing steps to modulate a single transport stream (or baseband frame) into a complex I/Q signal for input to a pair of DACs, or an interpolating DAC device such as the AD9857(or AD9957). Optionally, the output can be selected as an IF to supply a signal DAC.
