From the real -time market data tools, we have seen that the heat growth of several DSP materials has been very eye -catching recently. There are long -term high -priced prices and newcomers.Although the market has been restored after the holiday, the demand has not improved much. Whether it can find some directions of the demand from these DSPs, let us look at it.

Adsp-21060LCW-160

ADSP-21060LCW-160 isADIIts SHARC series processor supports IEEE compatible with 32 -bit floating -point, 40 -bit floating -point and 32 -bit fixed -point mathematics operations. The peak floating -point computing performance is 120MFLOP. Instrument.The ADSP-2106X is based on the ADSP-21000 processor core. It is a complete film system. The highlight of the latter is to add 4MB dual-port SRAM and integrated I/O peripherals supported by dedicated I/O bus.

ADSP-21060LCW-160 is actually a very hot material. It has high heat in the first half of last year, and the price is more than 10,000 yuan for a long time.After the festival, the search volume of the material quickly rebounded, reaching more than 1,000 times a week. Although it was not the peak of the previous heat, it was worth noting that the rapid recovery was worth noting.The domestic inventory index of this material has been very low for a long time, which means that its market circulation is small, and the price of over 10,000 can be understood.In addition, the material was included in the "not recommended for new design" by the original factory, and entered the end of the life cycle, which also helped to help its high prices.

DSPB56367AG150

DSPB56367AG150 can be traced back to the era of Freescal. It is 24 -bit DSP. The target application is audio processing. Its computing capacity reaches 150 mIPS. It is currently listed by NXP as new designs.Earlier, the heat of the material was the highest in the third quarter of last year. This round of popularity began to emerge after the festival, reaching its peak in early March, and the price was at a high level near 145 yuan.

DSPIC30F2010-30i/SP

DSPIC30F2010-30i/SP quiltMicrochipIt is defined as "high -performance 16 -bit DSC", DSC compared to DSP, the difference between the processor and controller (PROCESSER).As the original DSC defined, the 30MIPS computing power that the material can reach is much lower than that of ordinary DSP, and it is built -instorageThe capacity is also lower.Compared with DSP that focuses on digital signal processing, DSC is biased towards control, such as motor drivers, so the requirements of computing power have been reduced.

DSPIC30F2010-30i/SP has risen rapidly during the month after the festival. The recent single-week search volume has reached more than 2000 times. Compared with the previous monthly peaks of only more than 1,000 times.Its domestic inventory data has also been higher with search volume, which means that the current demand is strong.

summary

The above three modelsADIAs well asMicrochipThe hot DSP of the NXP brand is very representative, and two of them are "not recommended for new design".The life cycle will end, which arouses the demand for stocking.But in addition to these, there are some hot DSPs recently, and there are some models with low search volume. Recently, the heat has risen, and from the latest "daily comprehensive index" of the core index In the short term, the phenomenon of surge in and returning to silence seems to have some temporary needs.

So what is the demand for DSP today?A possible way is AI -related applications, such as the cultivation of production AI algorithms, which requires a large amount of corpus or image data input. For the initial processing of this information, DSP must be introduced.High -performance DSP can perform floating -point operations, and can be used as the masterchipThe good combinations of GPU, NPU, ASIC, etc., the auxiliary system plays the maximum effectiveness.The name of the DSP means that it is best at performing digital signal processing tasks, which is different from MCU and SOC, which is also the main chip.

The difference between DSP, MCU and SOC

When it comes to DSP, it will naturally think of the same processorchipMCU and SOC.The most common MCU in the general category is the meaning of a microcontroller. It has a processing unit, memory, and various analog peripheral interfaces in the internal packaging. "Single machine".Because of its computer structure integrity, the MCU is often used for controlling applications, such as small appliances, such as small appliances,robotArms, and wiper, etc.carThe operation of the peripheral components requires the MCU.

The representative MCU products include the AVR series of ATMEL,MicrochipPIC series, TI's MSP430 series,STSTM8 series, etc.ARMAs an emerging architecture, the most representative product isST M32 series, and NXP's LPC series.

The DSP index signal processor emphasizes computing power, fixed -point and floating -point computing performance is stronger than MCU, mainly for digital signal processing, such as image signals and audio signals.DSP can be compared with CPUs, all professional processingchipTherefore, dependence on external construction to achieve the best performance.In contrast, the complete peripheral of the MCU can independently implement the control function. Of course, if you need better performance, you can also build an outer peripheral.At present, the rise of AI applications, high -performance DSP can often use its powerful floating -point computing performance to assume the processing of images and corpus materials.The most important DSP original factory is TI andADIEssence

There is also a type of DSCchipCompared with DSP, the computing power is usually lower, and the peripherals are comprehensive. It is more important to play its control attributes, or it is specifically defined as a lower -performance DSP.For example, Ti's C2000 series is now defined as DSC by the original factory instead of DSP. The representative model is TMS320F2833X, which has long been highly popular for a long time.

The integrated system on the SOC indicator is also a single film attribute, but currently uses SOCchip, Generally refer to high -performance core chips, such asappleA series,QualcommSnapdragon et al.cell phonechipThey are generally made of advanced wafers.As various core chips are introduced more and more advanced processes, the boundaries of SOC, MCU and other categories are also blurred.
