Hardware Architecture

Myka is driven by the Sigma Designs SMP 8635.  This is a SOC.  It provides CPU and digital signal processing capabilities.  All of the signal outputs provided by Myka come directly from the SMP 8635.  All the other compents; hard drive, networking, memory are standard components.

SMP 8635 Details

The SMP 8635 is a high-definition satellite, cable, and IP set-top box DVR solution offering integrated AVC (H.264/MPEG-4 Part 10), MPEG-2, DivX, MPEG-4 Part 2 SD SP/ASP, and VC-1 video decoding technology. It combines a data transport processor, high-definition AVC/MPEG-2/MPEG-4/DivX/VC-1 video decoder, advanced-audio decoder, 2D graphics processing, high-quality video scaling and motion adaptive deinterlacing, six video DACs, stereo high-fidelity audio DACs, a MIPS32/MIPS16e class CPU, and a peripheral control unit providing a variety of set-top box control functions.

The MPEG-2 DVB-compliant transport stream/PES parser and demultiplexer is capable of simultaneously processing 256 PIDs via 128 PID channels in up to five independent external transport stream inputs and two internal playback channels. All 128 PID channels can be used by the record, audio, and video interface engine (RAVE), PCR processing, message filter, and for output via the high-speed transport or remux module. The data transport module can be configured to support eight record channels for PVR functionality and six AV channels to interface to audio and video decoders.
