Audio & Video

We can add Audio and Video capability to any single board computer or other embedded device. Our senior engineer worked for the BBC in its "Studio Planning and Installation Department" and has acquired great expertise in Audio and Video.

For the Audio we can use either Pulse Width Modulation or Digital to Analogue Conversion. In either case the output device can be Direct Memory Access driven or Interrupt driven. If desired, a custom FPGA can be used to offload the Audio function completely, with the Microprocessor only setting up the sound to be played and receiving an interrupt upon completion of that sound.

For the Video we can employ ready made chips such as the Epson S1D13806 or we can create a custom video output chip using an FPGA with a following triple high speed Digital to Analogue converter to drive the VGA cable.

Depending on the size of the video buffer provided and the depth of colour, high speed animation is possible. We have built custom video to be used with spinning reels in a "Slot Machine" SBC.

The colour depth can be from only black and white (no grey) with 1 bit all the way to sixteen million colours with 24 bits.
