High-speed, high-intensive data processing needs continue to challenge the performance limits of DSPs. How will the future of DSP evolve in response to these demands? A few days ago, in the communication with Lu Lei, the marketing manager of ADI's industrial department, the author found some answers. DSP presents five major trends Lu Lei believes that the development of DSP plays an important role in promoting the innovation of the next generation of products. In the future, DSP will present five major development trends. The first is the integration of DSP. More and more devices need to embed DSP functions. The implementation includes DSP core or hardware acceleration unit. The demand for DSP is mainly due to the increasing complexity of real-time algorithms and the trend of fixed-point algorithms to floating-point algorithms. As for why turn to floating point algorithm? Lu Lei said that there are three main reasons: First, many algorithms require more word length and a larger dynamic range. At this time, floating point has a natural advantage over fixed point. Second, product development and time to market are constantly shortening. Customers don't want to spend too much time doing fixed-to-floating conversion work. If they are implemented directly by floating-point algorithm, they can speed up the product launch. The third reason is that the cost of floating-point processors or floating-point algorithms is declining and getting closer to the fixed point. In addition, more and more DSPs are integrated with ARM processors. Although it seems that most ARM cores have limited real-time performance when implementing DSP signal processing tasks, integrating ARM cores is an inevitable trend in the future. At the same time, DSP also needs more and more interfaces, such as PCIe, Ethernet, etc. These interfaces are relatively complete on ARM processor platforms, but DSPs are traditionally more focused on algorithm performance and are not rich in interfaces. Meet the requirements of various connections. The second trend is low power consumption. DSP is not the better the performance, but the balance between performance and power consumption. For example, in many application scenarios, the heat dissipation of the system is very important, so it is not possible to blindly pursue high frequency or multi-core, and more needs to weigh the power consumption. The third trend is that DSPs are increasingly demanding software IP protection and secure network connectivity. Especially in the era of the Internet of Things, DSP needs to pay more attention to security features. The fourth and fifth major trends are more from customer needs. On the one hand, customers require products to be listed as soon as possible, on the other hand, higher reliability and long-term supply capacity are required. As product iterations are getting faster and faster, customers need to manage more and more code. At the same time, customers face more challenges in system integration, testing, and debugging. This is why DSP needs to be emphasized in the future development. Consider the issue. Dual SHARC+ core plus Cortex-A5 for improved industrial and real-time audio processing performance Based on these trends, ADI has introduced a new generation of SHARC processors for industrial and real-time audio processing (including industrial audio and automotive, consumer audio) applications. One of the most notable features of the previous generation is its SHARC+-based core, which offers a much higher performance than the previous generation SHARC core. The series includes 8 products, 5 ADSP-SC58x, based on dual SHARC+ core and ARM Cortex-A5 processor; 3 ADSP-2158x, excluding Cortex-A5, based on dual SHARC+ core only . The ADSP-SC58x and ADSP-2158x series consume less than 2W at high temperatures, making the new processor family more than five times more energy efficient than the previous generation and more than twice as powerful as the most competitive processors. In applications where thermal management limits power consumption, or can't tolerate costly, low-reliability fans, this advantage can lead to industry-leading digital signal processing performance, including automotive, consumer and professional audio, Multi-axis motor control, energy distribution system, etc. The FDSP and Neon DSP extended instruction set of the ADSP-SC58x products can handle additional real-time processing tasks and management peripherals to connect time-critical data in audio, industrial closed-loop control and industrial inspection applications. These interfaces include a Gigabit Ethernet interface (supporting AVB and IEEE-1588), a high-speed USB interface, removable storage (including SD/SDIO), PCI Express, and a variety of other connectivity options for a flexible and streamlined system design. ADSP-SC589 processor block diagram The ADSP-2158x family is targeted at applications that typically require a DSP coprocessor, including two SHARC+ cores and DSP accelerators, along with a set of peripherals that match the core. In the context of software intellectual property protection increasingly becoming a major security concern in the industry, the new generation of SHARC processors also introduces ARM TrustZone security features and an onboard cryptographic hardware accelerator. For applications where reliability is critical, data integrity can be improved with memory parity and error correction hardware. Lu Lei emphasized that the hardware acceleration unit is used because it needs to support FTI, iFFT, FIR, IIR, harmonic analysis is needed for power applications, and SINC filtering is required for motor control. These calculations are very large and can be accelerated by hardware. Enhance the processing power of the whole chip, and can support the floating point computing capability of up to 18GFLOPS in terms of FFT performance. Compared with the computing power of 5.4G SHARC+, the speed energy efficiency is 10 times and the power consumption is lower. In addition, it also consumes a lot of memory when performing cryptographic operations. If it is also a processor core that uses SHARC+, it is uneconomical. Hardware acceleration can not only achieve security, but also ensure overall performance. loss. Single-chip processor for multiple application needs According to reports, in the past, customers often need multiple chips when building a system using SHARC, and build DSP arrays through Linkport. However, with the development of semiconductor technology, customers' requirements for cost, size and power consumption of the system are constantly increasing, so integration has become a significant development trend. Today, a single chip integrated with the Cortex-A5 through the dual SHARC+ core, while using a low-power CMOS process, can reduce power consumption by more than 50%, BOM cost can be reduced by more than 33%, and board area can be saved by 60%. In automotive audio amplifiers, the performance of the single-chip ADSP-SC584 processor basically meets the system requirements. Nowadays, the application of microphones in automobiles is more and more, similar to noise cancellation, it is necessary to collect the source of noise first, and then do the corresponding digital signal processing. This requires a lot of audio channels, including speakers and microphones, and on the other hand requires strong digital signal processing. In terms of professional audio digital mixers, professional audio has low, medium and high-end divisions. The number of processors selected by customers is different depending on the processing performance. For very high-end professional audio digital mixers, an MCU+DSP array is required. Because the amount of computation is very large, you can use ADSP-SC589 as the processor. If you need further performance expansion, you can seamlessly connect ADSP-2158X through linkport. In industrial motor control, common motor control may require a smaller ARM processor. But for relatively high-end motor control, such as reluctance synchronous motor, not only need to drive the motor, but also some motion control algorithms, this time high-performance SHARC+ is useful, if you need two-axis, three-axis position Controlled operations, this time also requires an FFT hardware acceleration unit. As industrial Ethernet will be a trend in the future, real-time industrial Ethernet will increasingly use ADSP-SC58X series processors, due to Gigabit Ethernet, and support 1588 synchronous Ethernet, after industrial control When the data is transmitted, it has real-time and high speed. Similarly, PCle and asynchronous bus can also expand more Ethernet, because in some application environments, customers need more Ethernet to expand the system, the processor has high internal throughput, so in the ether There will be no bottlenecks in terms of network expansion. Open source operating system is an inevitable trend in the industrial field The development tools of the ADSP-SC58X and ADSP-2158X are mainly divided into software and hardware. The software part integrated development tool CCES (CrossCore Eembedded Studio), which is characterized by seamless integration of ARM and SHARC+ debugging environment, can simultaneously debug SHARC+ and ARM in the same environment. On the hardware side, ADI introduced the SC589 evaluation version and the ICE-1000 emulator. Lu Lei emphasized that the more complex the processor, the higher the user's requirements for the operating system. Therefore, ADI provides two operating systems for users to choose from. One is μC/OS2 or μC/OS3, which can run on ARM or SHARC+. The core is characterized by very good real-time performance and is a relatively lightweight real-time operating system. Another more complex operating system is ucLinux, which provides a complete ARM-based operating system and ARM's toolchain. As for why an open source operating system is used, rather than a well-known operating system such as Wind River, which has been used in the industrial field for many years? Lu Lei said that in the future industrial field, the open source system will be more promising. As customers' technical capabilities improve, they increasingly expect to have more intellectual property rights, and the same is true for operating systems. They want to be able to master them entirely, rather than buying existing systems. Existing customers such as power monitoring, high-end servo drives, and motor control have begun to use open source operating systems, which is an inevitable trend in the future.
