White Paper on TIE - Tensilica Instructin Extensions

TIE, Tensilica’s Instruction Extension language, is a simple way to make Xtensa processor cores faster and more efficient by adding new task-optimized instructions and I/O interfaces. TIE looks a lot like Verilog, but anyone can learn the basics of TIE in a few minutes whether they already know how to write Verilog descriptions or not. Just a few lines of TIE can make a dramatic difference in an Xtensa processor’s performance and flexibility for targeted tasks. Xtensa processors with TIE customizations can compute and move data tens or hundreds of times faster than conventional processor cores. As a result, your SOC gets smaller, cheaper, and faster and it will consume less power. Read the white paper to find out more.

White paper: Highest MHz Does Not Mean Highest Peformance

In fact, processors with high clock rates consume much more power because power dissipation rises faster than operating frequency. All major PC CPU vendors now offer multicore processors that run at lower clock frequencies than older generation single-core processors.

The same argument holds true for embedded processors, which is even more important for embedded products that operate under very tight power/energy budgets such as portable devices-because extending battery life is an important feature that improves product marketability-but it is also true for non-portable devices because consumers do not want noisy cooling fans in their set-top boxs or flt-panel televisions while IT managers want routers and switches that reduce electrical costs by minimizing energy consumption in the data centers. For these reasons, SOC development teams need to achieve performance goals while keeping a lid on clock rates.

White Paper: Why High MHz Does Not Mean High Performance

Traditionally, performance has been associated with higher frequency. However, higher performance can be achieved even while running the processor at lower frequency. This leads to not only lower power, but also to better architecture-performance efficiency and lower area. This lower area in turn leads to even more power savings when compared to traditional deep-pipeline RISC processors. Read this white paper to find out more

Use Customizable Processors as SOC Building Blocks

General-purpose microprocessor cores can’t deliver the application throughput, cost, and power efficiency needed for most computationally demanding embedded SOC tasks. These processors aren’t designed to efficiently manipulate audio, video or network packets or do other highly specialized tasks.

Until now, these demanding tasks had to be hard coded in RTL to get the speed required. However, designing millions of gates in RTL takes too long, is too hard to verify, and can’t be changed once the chip is fabricated.

Now there’s a real alternative to RTL design. You can use configurable, extensible Xtensa processors instead of RTL to finish your design much faster and add flexibility to adapt to changing standards or product requirements. Tensilica’s Xtensa processors provide both the I/O throughput and the computational performance previously only available with RTL design.

Speeding Basic DSP Functions - FFT Example Ap Note

This is an introduction and tutorial to techniques applicable to accelerating the radix-2 FFT, using TIE techniques that are simple and easy to implement. This document discusses a basic, but very powerful capability of TIE, the ability to define a register file of any arbitrary width and instructions that perform computations on the register file. Additional techniques, such as FUSION and SIMD, are introduced to show how to further improve performance, along with techniques to reduce gate count. These TIE techniques improve FFT performance by a factor of almost 100 times compared to a conventional processor. While the radix-2 FFT algorithm was chosen to illustrate the use of TIE on a relatively simple DSP algorithm, the techniques covered in this application note apply to accelerating any algorithm.

Reflections on Cadence Acquisition of Denali

Today Cadence announced that they were acquiring Denali to help fulfill their EDA360 vision. Cadence is far behind Synopsys in providing the entire 360 design view. Way back in the early '90s Synopsys made a huge investment in their DesignWare products, which continues to this day (I was the director of corp. comm at Synopsys from '93-'96).

It's good to see Cadence executing on their vision. Maybe we should expect other acquisitions as well? Who's next?

White Paper: A Designer’s Guide to HD Video Pre- and Post-Processing

HD video encoding and decoding algorithms get the bulk of attention by designers developing such products, but HD video codecs for advanced video applications such as broadcast television and Blu-ray disc players have quickly become standardized; there’s little room for product differentiation in a standardized video codec. However, you can substantially differentiate an HD product’s design by improving the video image stream—both before video compression and after.

Using Multiple Processors in the SOC Dataplane

There are several advantages to using multiple processors as SOC task building blocks. One of the biggest is that processors are inherently programmable, so functional changes can be made to the chip’s operation using firmware after the chip design is finished and even after the chip has been fabricated. Complex state machines can be implemented in firmware running on the processors, greatly reducing verification time.

In addition, a multiple-processor-based design approach promotes the flexible sharing and reuse of on-chip memories while reducing the overall amount of memory needed.

Design with multiple processors facilitates system modeling with instruction-set simulators, which are much faster and more efficient than RTL-based system simulation. Read more about it here.

CTO Chris Rowen Speaking at CoolChips XIII in Yokohama, Japan

On Wednesday, April 14 at 10 am Dr. Rowen will discuss "Resolving the Grand Paradox: Low Energy and Full Programmability in 4G Mobile Baseband SOCs". On one hand, increased mobility dictates smaller batteries, longer battery life and improved energy efficiency. On the other hand, the complexity of new baseband standards like LTE - plus the multimedia, network protocols and application services enabled by fast baseband - dictate increased programmability, ubiquitous multi-core and more software layers. Rowen will describe practical successes for ultra-low energy processors used for LTE PHY subsystem designs achieving 150Mbps data rates in less than 250mW. And he will conclude that resolving this paradox has a domino effect on wireless infrastructure, DTV and wired communications.

ConnX D2 Delivers Outstanding 16-bit Fixed Point DSP Performance on Compiled C Code

No need for assembly code optimization. This allows SOC development teams to have greater flexibility in resource allocation as well as the ability to quickly change algorithms. C code optimized with TI C6x or ITU C intrinsic functions compiles directly to the ConnX D2 instruction set, allowing developers to benefit from pre-existing TI and ITU code bases.

The ConnX D2 option adds dual 16-bit multiply-accumulate (MAC) units and a 40-bit register file to the base RISC architecture of the Xtensa LX processor. The ConnX D2 engine utilizes two-way SIMD (single instruction, multiple data) instructions to provide high performance on vectorizable C code. It also delivers dual-MAC performance using 64-bit VLIW (very long instruction word) instructions for code that cannot be vectorized.

Why Designers Need a New DSP for SOC Designs

The rapid changes in wireline and wireless communications, disk drives, home entertainment devices, and computer peripherals are driving demand for 16-bit fixed-point DSPs. Stand-alone DSP chips are no longer cost effective for most of these price-sensitive applications. Instead, there's growing demand for general-purpose 16-bit DSP engines that can be easily designed into highly integrated SOC silicon.

At the same time, the growth of multiple standards and the complexity of these standards is driving developers away from traditional assembly-code programmed DSPs towards integrated architectures that combine excellent DSP performance with generalized high performance when developing with compiled native C control code.

The market needs a DSP engine that can easily be customized if necessary, integrated into a SOC design, and programmed most often in C, rather than assembly code. This will help speed new products to market as quickly as possible.

Why High MHz Doesn't Necessarily Mean High Performance

Read our white paper. Traditionally, performance has been associated with higher frequency. However, higher performance can be achieved even while running the processor at lower frequency. This leads to not only lower power, but also to better architecture-performance efficiency and lower area. This lower area in turn leads to even more power savings when compared to traditional deep-pipeline RISC processors.

White Paper: A Designer’s Guide to HD Video Pre- and Post-Processing

HD video encoding and decoding algorithms get the bulk of attention by designers developing such products, but HD video codecs for advanced video applications such as broadcast television and Blu-ray disc players have quickly become standardized; there’s little room for product differentiation in a standardized video codec. However, you can substantially differentiate an HD product’s design by improving the video image stream—both before video compression and after.

Back to Basics: Using Processors in the SOC Dataplane

Read the whitepaper. Designers need a quick, fool-proof way to customize those processors for the exact task at hand. A dataplane processor (or "DPU") naturally connects to existing RTL blocks and provides additional computational horsepower tailored to the exact data type needed - all this with less effort than hand-coding RTL finite state machines or microcoded engines.
