Tensilica HiFi 3z DSP IP Core Provides Enhanced Voice and Audio Processing

Cadence Design Systems has announced the Cadence Tensilica HiFi 3z DSP IP core for system-on-chip (SoC) designs targeted for the latest mobile and home entertainment applications, including smartphones, augmented reality (AR)/3D goggles, digital TVs and set-top boxes (STBs). The new HiFi 3z architecture offers more than 1.3X better voice and audio processing performance than its predecessor, the HiFi 3 DSP, which leads the industry in the number of audio DSP cores shipped.

Higher voice sample rates require more complex voice pre-processing. Enhanced Voice Services (EVS), the latest mobile voice codec supporting voice over LTE (VoLTE), supports up to a 48kHz sample rate, compared to 16kHz for the previous AMR-WB codec. The new HiFi 3z DSP delivers more than 1.3X better performance for EVS than the HiFi 3 DSP core. Home entertainment is driving a similar workload increase as audio codecs like Dolby AC-4 and MPEG-H transition from channel-based to object-based. In addition, audio post-processing functions such as Waves Nx 3D/AR audio and the immersive audio of Dolby Atmos-enabled TVs are driving higher complexity signal processing. The HiFi 3z DSP provides more than 1.4X better performance on Dolby Atmos-enabled TVs than the HiFi 3 DSP.

The HiFi 3z DSP offers a number of architecture and instruction set architecture (ISA) improvements over the earlier HiFi 3 DSP, including:

– Dual load/store

– Advanced FLIX bundling (multiple-base ISA operations per cycle)

– Double the MACs for 16×16 (octal MAC)

– Enhanced ISA for accelerating FFTs, FIRs and IIRs

– New instruction extensions to improve codec (especially EVS) performance for mobile

– 4-way, 8-bit load for improved voice trigger performance

– 8-way, 8-bit load for reduced neural network memory usage

Tensilica HiFi DSPs are the most widely licensed audio/voice/speech processors, with support for over 200 proven software packages and more than 95 software partners in the Tensilica Xtensions partner program. More than 75 top-tier semiconductor companies and system OEMs have selected Tensilica HiFi DSPs for their audio, voice and speech products.

8-Bit Microcontroller IP Core

DigitalCoreDesignThe DF6808 IP core is binary-compatible with the industry-standard Motorola 68HC08 8-bit microcontroller. The IP core uses sophisticated on-chip peripheral capabilities to perform 45 to 100 million instructions per second. FAST architecture implemented in DF6808 enables the 68HC08 microcontroller to run at least three times faster than the original solution.

The DF6808’s 16-bit, free-running timer system has two input-capture lines and two output-compare lines. The IP core is equipped with proprietary safety functions, including self-monitoring circuitry, which helps protect against system errors; the computer operating properly (COP) watchdog system, which protects against software failures; and an illegal opcode detection circuit, which provides a non-maskable interrupt if an illegal opcode occurs.

For power conservation, the IP core includes two software-controlled power-saving modes (Wait and Stop). These modes make the DF6808 IP core well suited for automotive and battery-driven applications.

The DF6808 includes the DoCDTM real-time hardware debugger, which provides built-in support for Digital Core Design’s hardware debug system and the debugging capability of an entire system-on-a-chip (SoC). The DoCDTM enables nonintrusive debugging of running applications. It can halt, run, step into, or skip an instruction and read/write any microcontroller contents, including all registers, user-defined peripherals, data, and program memories.
