IVL Technologies' On-Key Karaoke Handheld Player Sings along with the Nucleus RTOS Kernel

The On-Key Karaoke Handheld Player is a karaoke microphone that plugs into a TV and allows a person to sing along with many of their favorite songs. The Karaoke microphone contains many innovative features such as tempo control, pitch correction, harmony, key control of the music played and transformation of the voice to the opposite gender. The Karaoke Player comes with 50 songs built in to the microphone. By connecting to the Internet, a person can download additional songs so there is never a chance of running out of tunes to sing.

Nucleus selected for the On-Key Karaoke Handheld Player

IVL Technologies purchased a development package based on the Nucleus RTOS from an image and audio processor technology company, Sound Vision Inc., which includes an ARM7 TDMI-based chip called Clarity 4. Sound Vision provided IVL with a reference design that was modified by IVL to create a Karaoke microphone that plays songs stored in MIDI format. Included in that development package was the Nucleus RTOS kernel .

The Nucleus RTOS kernel is reliable and scalable; developers can scale the kernel down to as small as 17KB, including both code and data sizes, for the ARM7 processor. This is important for feature intensive consumer electronics applications such as the On-Key Karaoke Handheld Player. Additionally, with Mentor Graphics' flexible business model, developers using Nucleus RTOS could meet the price expectations of the consumer marketplace.
