Shanghai, China, July 26, 2017 - NASDAQ: CDNS today announced the launch of the Cadence® Tensilica® HIFI 3Z DSP IP core designed for the latest mobile and home entertainment applications . Its applications include smartphones, enhanced reality (AR) / 3D glasses, digital TVs and set-top boxes (STB), etc. Compared to the previous generation of the previous generation of HIFI 3 DSP, the new HIFI 3Z architecture will provide more than 1.3 times stronger voice and audio processing performance.
Higher voice sampling rate requires more complex voice pretreatment, Enhanced Voice Call Service Codec (EVS) is the latest 4G HD voice Volte mobile phonetic decoder, which supports the sample rate of up to 48kHz, and before The sample rate of the AMR-WB codec is 16kHz. The new HIFI 3Z DSP treatment EVS performance is 1.3 times higher than HIFI 3 DSP. Similar calculation workloads are also reflected above, such as Dolby AC-4 and MPEG-H, etc. Audio codecs are converted from the channel to object-based audio. In addition, the 3D / AR sound algorithm such as WAVES NX can support Dolby Dolby Atmos, such as an immersive sound TV, and the audio post-processing function is pushing higher complexity signal processing. Compared to HIFI 3 DSP, HIFI 3Z DSP has increased 1.4 times more than 1.4 times the performance of the TV that supports Dolby ATMOS.
"Waves continuously developed technology combination and Cadence's new generation of efficient HIFI 3Z DSP kernels, so that we can continue our mission, provide the tip audio capabilities to consumers anytime, anywhere," WAVES AUDIO consumer electronics department President and General Manager Tomer Elbaz said. "Waves' algorithm has increased by 20% in HIFI 3Z DSP. Combine our multi-function audio processing algorithm, providing very attractive solutions for manufacturers who wish to provide exceptional audio experiences for their customers. "
HiFi 3Z DSP provides many architectures and instruction sets (ISA) improvements compared to the previous version of HiFi 3 DSP, including:
Dual loading / storage (LOAD / STORE)
High-order FLIX combination (executing multiple basic operating instructions per cycle)
Double 16x16 Mac (Eight Road Mac)
Enhanced instructions for accelerating FFT, FIR, and IIR calculations
New instruction extensions, lifting mobile app codecs (especially EVS) performance
Four-eight-bit loading is used to improve speech trigger performance
Eighth-eight-bit loading to reduce the memory required for neural network applications
"To pursue a better consumer experience, new audio and speech codecs and front and rear processing function algorithms, the signal processing and control code workload follows," Cadence Company Audio / Voice IP Marketing Director Larry Przywara said. "We designed HIFI 3Z DSP to effectively support these new audio and speech computing requirements. HIFI 3Z DSP has been authorized to users, and its mobile SOC has flowed and is expected to be produced in 2018."
The Tensilica HiFi DSP family is the most widely used audio / sound / voice processor that supports more than 200 validated packages, with more than 95 software partners in the Tensilica XtensionsTM partner program. More than 75 top semiconductor companies and system OEM manufacturers have chosen Tensilica HiFi DSP to use them for audio, sound and voice products.
