Latest EDA update from Cadence: 3D audio DSP, memory, interface IP and AMS tool

Tensilica HiFi 4 audio/voice digital signal processor (DSP) intellectual property (IP) core from Cadence supports new and interesting object-based audio standards, where individual sounds become objects that can be placed anywhere in a room. The separate sounds sources are mixed on the fly at each location where they are played back. DSP calculates where the sound should emanate irrespective of location of speakers . Single core HiFi 4 DSP -based chip is capable to handle such processing. HiFi 4 DSP supports four 32x32-bit multiplier-accumulators (MACs) per cycle with 72-bit accumulators, more than double the performance of other audio DSPs for computationally intensive functions such as fast Fourier transform (FFT) and finite impulse response (FIR) and also supports for eight 32x16-bit MACs per cycle under specified conditions, as per Cadence. HiFi 4 DSP also offers 4 very long instruction word (VLIW) slot architecture capable of issuing two 64-bit loads per cycle. Another music related interesting feature in Cadence Tensilica HiFi Audio/Voice digital signal processor (DSP) family is HARMAN’s Clari-Fi music restoration technology has been ported to these cores. HARMAN’s Clari-Fi music restoration technology automatically analyzes and improves the audio quality of all types of compressed, digitized music sources, reconstructing the information lost during the compres...
