From 90nm, to 65nm, 45nm, and then to 32nm, the advancement of manufacturing technology makes the processing performance of DSP increase rapidly in accordance with Moore's Law. Dual-core and even six-core make the performance of DSP easily doubled. This performance improvement makes DSP in some applications Stuck in an embarrassing situation of excess MIPS processing power. At the same time, MCUs and FPGAs also benefit from technological advancements, and can partially or even completely replace DSPs in some applications. Dong Yonghong, general manager of Wenting Digital System (Beijing) Co., Ltd., believes that DSP is facing a turning point in the development of the market and technology due to the adequate supply of the market. The nobles in the original chip market have gradually become popular products that anyone can use. The upstream IC manufacturers have even completed the software, which makes it more difficult for the downstream system manufacturers to achieve software differentiation. Sometimes they have to wait for the appearance. Get some creativity in design that has nothing to do with functions. Mobile phones are a typical case. Processing device architecture evolution Dong Yonghong said that the future market may be a functional-level SOC with a programmable DSP. The upstream semiconductor factory completes 80% of the work, and the downstream system factory completes the remaining 20%. He likened this kind of change to the DSP 2.0 era, which is marked by no longer taking computing power as the starting point, but focusing on functions. In the future, companies that have algorithms and the ability to engineer algorithms will win out. This is what distinguishes them from other vendors. For products with high demand, semiconductor factories will provide both hardware and software, leaving room for intermediate development companies to become smaller and smaller. Functionalization corresponds to application. Dong Yonghong believes that DSP will become DXP in the future. D refers to the digital signal of the physical layer in general, and X is a specific application. DXP reflects that DSP with strong data processing capabilities is no longer the core problem of the system after the supply of DSP is sufficient. People focus on the integration of the signal chain, including front-end data acquisition. DM355, DM365, and DM357 are all excellent products that embody functionalization. The reason for the success of TI's C28x series is to integrate the entire signal chain into one chip, including ADC and DAC. DM642 is an IP core that integrates image preprocessing and also embodies the concept of signal chain. Typical device DLP For example, Dong Yonghong, TI’s DLP is a typical DXP. This purely digital optical processing device has occupied more than 50% of the projector market with its rich and accurate color synthesis, high brightness and long life. It is in the digital cinema market. The share is 100%. Large-screen high-definition rear projection is a market with great potential for DLP. Sharp has launched a 65-inch high-definition rear-projection TV using LED as the light source in the United States. The price has a clear advantage over LCD TVs of the same size. In addition, because DLP is a spatial light modulator, it can also be used in applications that have a relatively high degree of optical relevance, such as three-dimensional imaging, spectrum analysis, PCB printing, and has the opportunity to give birth to many new applications related to light. For example, a foreign company adopts DLP to realize image acquisition of human face, and uses DLP projector to illuminate the blood vessels of the arm to assist nurses in giving injections to patients. Wenting is collaborating with domestic research institutions on DLP application projects to give full play to Wenting's technical advantages in DSP and video image processing. The current difficulty is to solve the problems of DLP device management and control, image processing, optical engine, and light source. DLP is still in the early stage of market promotion in China, and Wenting's main business is still centered on DSP, especially to solve practical problems encountered by customers in the process of using DSP. Ruwenting’s test and programmer can test and program the chip before the chip is soldered to the PCB board. It has its own upper computer operation interface, as long as it is connected to the upper computer through the USB cable, without emulator and CCS. The chip is programmed to meet the needs of factory and mass programming. Innovative design of embedded graphics Another innovation of Wenting is the introduction of a DSP+ display chip solution, called an embedded graphics card, which can easily make a user-friendly interface. The display chip is designed by a semiconductor company in Silicon Valley to complement the display function of the DSP. The user copies the data to the memory of the display chip, and the rest of the work such as display drive, image processing, and interface is completed by the display chip. Wenting is developing a universal embedded module using PC104 Express bus to complete the collection, processing, display, storage, transmission, interface, control and management functions on the motherboard. Wenting will provide 8 to 10 acquisition modules, and the processing module will provide commonly used general DSP modules, such as floating-point DSP and fixed-point DSP. The user directly stacks the main board, acquisition module, and self-developed data processing module together to form a complete embedded system. The advantage of using a motherboard based on a general-purpose processor is that it can directly use the abundant software resources on the PC, eliminating the need for software migration and optimization, and it is guaranteed in terms of operating system support, hardware compatibility, and supply stability. Time and cost can also be greatly reduced. This mode is especially suitable for small batches of customized applications. Wenting is also using its advantages in video processing to develop a Skype-enabled video phone based on this architecture, so that users can enjoy communication services provided by operators without PC connection. Dong Yonghong further stated that traditional DSP development tools, DSP+ display chips, and general embedded modules can be summed up as Wenting's ABC strategy to help users achieve differentiated functions.
