DENAFRIPS DAC is equipped with Intel Cyclone® IV E FPGA, Field Programmable Gate Array. The software running in the FPGA is called firmware; a specified, purposed-built operating instructions the DENAFRIPS DAC uses. It is the heart of the DAC where complex Digital Signal Processing is happening in the FPGA. One of the beauties of the FPGA (Field Programmable Gate Array), as the name suggested, it is Field Programmable. DENAFRIPS DAC's FPGA firmware can be updated by using a Windows OS or MacOS computer over the USB port by a person with good computer knowledge. Most customers will be able to do it because it's fairly straightforward.
12th ANNV. FPGA FIRMWARE To commemorate DENAFRIPS’s 12 years of digital audio excellence, DENAFRIPS engineers have been working on a new 12th Annv. FPGA Firmware to improve the sound quality, add features, bugs fixed, update software and keep your device up-to-date. Areas of Improvement:
Improved Adaptive FIFO Buffer & Reclocking Architecture
Reduced the effect of Buffer overrun/underrun due to the Source's Clock and the DAC's Clock differences
Reduced Audio Latency
Reduced Phase Difference between L/R Channels
Optimised DSP to improve the sonic performance
We will be rolling out the firmware by stages, starting with the Ares II / Enyo DAC. Note: Firmware(s) for the Pontus / Venus / Terminator II/Plus will be rolled out at a later date.
