This section will provide an overview of the applications and working principles of the LMH1218EVM.

Application Field

The LMH1218EVM provides a complete solution for audio processing, streaming and image processing applications. It is ideal for audio system development, embedded systems and video streaming. The LMH1218EVM combines Texas Instrument’s C6-00B DSP processor, a modern SDRAM, and a powerful ARM Cortex-M4 core to deliver a high degree of performance.

The LMH1218EVM supports a broad range of audio, voice, imaging and streaming applications, including speech and music processing. It provides a versatile platform for applications such as Vocaloid or Digital Audio Workstations (DAWs) created by Yamaha and Roland.

Furthermore, the LMH1218EVM provides a comprehensive platform for developing video streaming applications such as motion picture capture and delivery via streaming on internet sites. It will also be useful in concert and theatrical performances, music video editing, motion graphics, and digital signage.

Working Principle

The heart of the LMH1218EVM is the Texas Instruments OMAP-C6-00B processor, which is a low-power ARM Cortex-M4 microcontroller, incorporating a 32-bit RISC processor, as well as an advanced floating-point floating-point unit (FPU). The OMAP-C6-00B processor provides an impressive array of peripherals, including GPIO, UART, I2C, SPI, LCD, and camera, as well as USB, Ethernet, and Wi-Fi support.

The C6-00B processor utilizes the Texas Instruments’ Stream Loader DSP Loader to allow loading of software programs (into the DSP memory) over a USB connection. The software packages provided with the LMH1218EVM are all optimized for the C6-00B processor, resulting in higher throughput rates compared with standard non-optimized programs.

The LMH1218EVM also incorporates a variety of other peripherals, including a Texas Instruments C6-00B DSP Cipher module, a Micro SD memory card slot, and a Micro HDMI connection. The C6-00B DSP Cipher module provides an encryption/decryption sequence and configuration to ensure secure audio and video playback.

The board also incorporates an AMP for high-fidelity audio outputs, an HDMI connection, and a MicroSD slot for storing audio/video data. The onboard AMP is capable of driving audio signals up to 2 W RMS output power of 8 Ω loads.

In conclusion, the LMH1218EVM is a flexible and comprehensive evaluation and demonstration board that can be utilized to deliver powerful audio, video and image processing applications and solutions. The ability to quickly start working on a design and to understand the underlying system platform quickly and easily makes the LMH1218EVM an ideal choice for engineers working in audio, video and other related fields.
