The DVF2300 is DSP Group’s latest-generation system-on-chip (SoC) for video and voice over IP (V2oIP) solutions. This design provides an ideal solution for high-end voice and video conferencing terminals with rich and innovative GUI, UHD (4K) video streaming and other multimedia content targeting media IP phones and high-end voice assistant enabled conferencing systems.
The DVF2300 is equipped with a high-performance Arm Cortex-A53 quad-core CPU with 1M L2 cache embedded. The DVF2300 also integrates an efficient Arm T820 graphics processing unit (GPU) to accelerate 2D and 3D graphics processing, which achieves performance competitive with the Mali-450 8-core configuration. For acceleration of the OSD and 2D user interface, the built-in streaming engine of DVF2300 provides commonly used drawing functions. The CPU is dedicated to applications, while most of the functions of the DVF2300 utilize separate hardware circuits to provide efficiently optimized systems. The video DSP of DVF2300 is dedicated to manipulating, decoding, and encoding video streams in various formats, for example, decoding 4K2K, H.265, full HD MPEG1/2/4/H.264/H.264, MVC, AVC/VC-1, VP8, and HD JPEG, etc. Video decoding and encoding can run simultaneously.
Additionally, video post processing on the DVF2300 is handled by a video processing subsystem that supports 3D de-interlacing, video scaling up to 4K2K and so on. Audio decoding is carried out by an audio DSP that is capable of decoding a set of audio formats, e.g. DTS HD, Dolby® Digital Plus, TrueHD, and other popular formats. The audio DSP also performs audio post processing.
The DVF2300 provides a secure environment for a rich operating system, bringing UHD and HDR content to big screens. A secure video path and secure storage are fundamentally essential to secure systems. With the deployment of Arm TrustZone and the implementation of a proprietary security mechanism, DVF2300 protects video and highly confidential information from leaks. An independent secure operating system runs on DVF2300. In addition, DVF2300 hardware offers a cryptography engine, true random number generator (TRNG), and sufficient one-time programmable (OTP) ROM space, which are elements critical for a trusted execution environment.
The DVF2300 supports a comprehensive set of peripherals, including an integrated HDMI transmitter and receiver with PHY. The HDMI interface supports HDCP. Other interfaces include USB2.0/USB3.0 host/device with PHY integrated, NAND/NOR/eMMC flash controller, card reader supporting SD/MMC, high-speed UART, Gigabit Ethernet MAC and PHY, 4-bit SDIO, IrDA receiver and transmitter, and dual transport stream interfaces.
This innovative and feature-rich SoC consumes low power and is available at a competitive price.
DSP Group’s field-proven IPfonePro SDK along with its sophisticated set of audio and video algorithms are incorporated in the SDK available on DVF2300. This SDK includes various audio/video codecs, an acoustic echo canceller, superior audio algorithms and audio tuning tools – all fully compatible with other DSP Group V2oIP chipsets.
