Synopsys Enhances ARC Processor Core With Superscalar, DSP Capabilities

By adding a second front-end instruction decoder to the ARC HS3x high-end 32-bit RISC architecture, along with doubling the number of ALUs, Synopsys has created its latest ARC HS4x processor IP core family (Figure 1). The estimated performance increase over an ARC HS3x predecessor at the same clock speed can be as high as 40%, according to the company, with only modest die size and power consumption impacts. And via the inclusion of DSP enhancements akin to those initially launched with the mid Read more...

Microsoft’s Deep Learning Toolkit Advances

Microsoft's Cognitive Toolkit (formerly CNTK) is a relatively recent entrant to the open-source deep learning framework market. And, as the company's Principal Researcher Cha Zhang acknowledged in a recent briefing, it has a ways to go before it can catch up with the population of developers enjoyed by well-known alternatives such as Caffe and Google's TensorFlow. Last year's transition from Microsoft's own CodePlex open source hosting site to the more widely known GitHub repository, along with Read more...

Case Study: Growing Your Business by Targeting New Markets

One key challenge for a technology company is identifying markets for its products. Let’s say you have an idea for entering a new market using your existing technology. How do you know if there’s a fit? How do you realistically assess your risk? With more than 25 years of experience evaluating embedded processing technology, BDTI often helps clients assess and improve technology-market fit to define new products and find new markets.  BDTI understands the market trends and competitive dynamics Read more...

Texas Instruments' SoCs Aspire to Bring Advanced Driver Assistance to the Masses

ADAS (advanced driver assistance systems) are rapidly being incorporated into automobiles and other vehicles, as products unveiled at January's North American International Auto Show in Detroit, Michigan made clear. Just a few short years ago, passive collision warning and active collision avoidance features were restricted to luxury models from luxury manufacturers. Now, even mass-market car suppliers are incorporating ADAS capabilities into their high-end and mainstream vehicles. In order for Read more...

ARC Processor Core Enhancements Promise Performance, Energy Consumption Improvements

In May 2014, Synopsys expanded its ARC EM licensable processor core product line, which BDTI described as historically being "vanilla" Harvard architecture CPUs with no DSP-optimized features, via the addition of the digital signal processing pipeline-equipped EM5D and EM7D (“D” denoting DSP). This year's follow-on EM9D and EM11D make what at first glance seem to be minor upgrades, in the form of an optional incremental 2-64 KB of special-purpose embedded memory. But, according to company Read more...

Case Study: Squeezing Big Algorithms into Small Power Budgets Enables Mobile Audio Quality

Today's smartphones are technological marvels that deliver an extraordinary range of capabilities from GPS-based navigation to sophisticated photography. But sometimes we just want to make a phone call. And particularly when we're on the move, who hasn't struggled to hear the other party or to be heard on a mobile call? Realizing the importance of intelligible phone calls – not to mention a strong need to differentiate their products – smartphone manufacturers are incorporating increasingly Read more...

Sensory Adds Deep Learning Support to TrulyHandsFree

Sensory's TrulyHandsFree software, which InsideDSP last covered at its v3 introduction in early 2013, precedes limited-vocabulary speech recognition with voice detection involving a specific key word or phrase. And with latest version 4.0, Sensory adopts convolutional (i.e. "deep learning") neural network (CNN) techniques. Jeff Bier began a recent editorial with the following statement: Lately, neural network algorithms have been gaining prominence in computer vision and other fields where Read more...

Analog Devices' SHARC Doubles Up, Adds ARM Option

The SHARC DSP family has long been a design staple of mid-range and high-end audio, industrial and other digital signal-processing intensive applications. With its two new series of products, Analog Devices delivers dual-core SHARC to the market for the first time. And the ADSP-SC58x devices also integrate an ARM processor core to tackle system control code functions (Figure 1). Figure 1. A migration from the 65 nm to 40 nm process node enables a high degree of integration in Analog Devices' Read more...

Cadence's Tensilica Fusion: DSP for the IoT

The "Internet of Things" (IoT), one of the hottest topics in technology today, is widely anticipated to be a notable driver of both semiconductor and software demand in coming years. Key to an understanding of the IoT opportunity, as a recent article published on the Embedded Vision Alliance website notes, is its machine-to-machine aspect. Content generated at the source end of the IoT communication link is created by devices using various sensor technologies, which are forecast to experience Read more...

Case Study: System Designers Selecting Multimedia Processors Benefit from BDTI Insights

Portable electronics devices are incorporating increasingly sophisticated multimedia capabilities, while at the same time striving to meet tough size, weight, battery life and cost requirements. Recently, a BDTI client launched a design for a new portable multimedia system requiring billions of floating-point operations per second and low input-to-output latency, and single-digit power consumption to enable compact and fan-less system operation. Robust software development tools were also a key Read more...
