VHDL based Xilinx FPGA Design
When retained as a consultancy, XiChron strives to become an integral element within our client’s engineering team. These clients often desire to maintain their confidentiality and we do our best to respect this. Here is a general overview of some recent projects:
AES Router Xilinx Chip Design
Design of 128 channel AES router Xilinx implemented in VHDL. Advanced switching, AES block management, and subcode functions. Basic Audio Processing also implemented on chip with a sample accurate synchronous control layer. Emerging standard in Radio and TV broadcast applications.
Advanced 24-Bit ADC/DAC Converter
Design and implementation of efficient DSP algorithms for an 8 channel, high performance, digital audio converter system. Considered the best in their class, these units are used throughout the professional audio, film and video industries. XiChron also engineered the user interface SW, running on an embedded controller.
24-Bit ADC and DAC
Analog and digital design of separate 24-bit audio DAC and ADC for high reliability backplane standard. Very high profile manufacturer in the TV and Radio broadcast markets. Met aggressive acceptance metrics in a harsh rack environment with switching power supplies. Also provided VHDL based Xilinx design for audio processing and I/O plus embedded microcontroller code.
Digital Audio Bus Implementation
Complete specification of proprietary TDM bus. Supports 128 channels of 24-bit audio with provisions for digital video. Implementation of reference interface FPGA design as well as several I/O boards, including ADAT litepipe.
Audio Test Instrumentation System
Design and coding of a PIC based audio test set. Creation of audio test signal CD. User interface and realtime test processing algorithm implemented in PIC microcontroller.
Windows95 Driver for Interactive Multimedia Game
Port of existing code over to non-standard Japanese PC architecture. Detailed coding of enhanced realtime driver. Support for vendor specific I/O devices.
Video Switch for Home Theatre Product
Multi format video switch and format conversion. Supported video standards included composite video, S-video and RGB. The video switch was one module within a very high-end Home Theatre system.
