How can emerging applications help DSPs regain “lost ground”?

The DSP market has been "squeezed out" over the years. On the one hand, with the continuous development of ARM, MCU has eroded the low-end DSP market which once occupied a large market share in industrial and consumer electronics; on the other hand, the programmability and high configuration of FPGA Sex also makes it erode some of the DSP market. Of course, DSP manufacturers will not be "smothered" in this regard. In recent years, they have continued to expand the advantages of DSP through innovation, develop high-end DSP to expand emerging applications, and strive to recover some "lost ground." Tang Xiaoquan, an industry expert, also said that embedded control has been dominated by past logic operations, and gradually transitioned to mathematical operations. The generalization of DSP signal processing is mathematical operation, so the DSP will change from the previous supporting role to the protagonist.

Multiple innovations to achieve breakthroughs

Integrate high-efficiency fixed-point and floating-point operations to achieve high performance and low power consumption in a smaller form factor.

Texas Instruments (TI), which is half the market in the DSP market, announced the launch of three new platforms based on the KeyStone multi-core architecture with the TMS320C66x DSP family, Gauss. Compared to previous DSPs, it combines efficient fixed-point and floating-point operations to achieve real-time performance at low power consumption in a smaller form factor. Zheng Xiaolong, TI's general DSP business development manager, told reporters, "This platform has achieved a revolutionary breakthrough: performance is faster; lighter, suitable for portable applications; smaller, due to higher integration, and more Accurate, more efficient and more economical."

All of this comes from its "single effort", the C66x DSP series uses KeyStone multi-core navigators, each with up to 1MB of dedicated L2 cache. "The advantage of L2 cache is that it can optimize the program and improve the processing efficiency. For the application, the internal memory is very helpful for the operation speed. If the memory capacity is not large enough, it needs to communicate with the external memory, which will affect Speed.” Zheng Xiaolong further pointed out that “at the same time, the memory system integrates 32B DDR3 and multi-core shared memory controller, which can effectively reduce power consumption.” In addition, the C665x DSP platform also provides RapidIO, PCIe and thousands. High-bandwidth serial ports such as Mega Ethernet, and can extend processing capabilities to a variety of DSPs.

Along with this, ADI recently introduced the dual-core, 1GHz processing capability of the Blackfin BF60X processor family, featuring two 500 MHz cores and up to 4.3Mb of on-chip SRAM, optimized for low-power applications. Among them, the "Lineline Vision Processor" equipped with BF608/BF609 is a high-performance video analysis accelerator, providing a total of 12 high-performance, flexible configuration signal processing modules, supporting various commonly used algorithms, providing extremely high object tracking and detection. And identify performance.

Broaden portable and high performance applications

DSP opens up new horizons in portable and high-performance applications.

In the past, wireless communication, industrial process control, and grid monitoring/protection were the markets of general-purpose DSPs. However, as real-time processing requirements for related applications increased, DSPs also achieved a perfect combination of "high performance and low power consumption" in the next generation of aviation. Electronics, embedded vision, car-assisted driving systems, video surveillance, etc. have opened up a "new world."

High-end DSPs are highly regarded in these areas and are “dancing” to meet market demands. Video applications are typical. Zheng Xiaolong said that with the deepening of video applications, new demands have arisen, such as the development of cameras from analog to IP, and the development of sensors from CCD to CMOS. Intelligent video surveillance involves not only video compression, but also intelligent identification to improve security. Sex, but also need to achieve video analysis in the front end, requiring high real-time. Zheng Xiaolong proposed to use a low-power high-performance DSP array, which makes the system more compact while maintaining low power consumption.

Biometrics is also an eternal topic for DSP. "For example, fingerprint recognition can be done with a low-end processor, because there is a fingerprint pattern, but now fingerprints are beginning to have new developments. It is necessary to combine sensors, so that more accurate sensors are needed to acquire signals, which requires high-end DSP. In addition, three-dimensional recognition, pupil recognition, etc. must use high-end DSP." Zheng Xiaolong said.

Of course, DSP vendors need to focus on future needs and provide flexible scalability. Lu Lei, ADI's DSP processing Asia regional manager, said that in the platform selection process, customers not only need to consider cost factors, but also need to consider different new requirements for complex applications, so platform scalability is an important issue, powerful, Low cost and energy efficient DSPs are key boosters for this technology. In addition, product development should be carried out on existing resources as much as possible.
