From the real-time market data tool "Creation Index", we can see that several DSP materials' popularity has recently grown very eye-catching. Among them, there are long-term high-priced materials, and there are also those that have recently surged in popularity. Although the overall popularity has recovered in the market since the holiday, the demand has not improved much. Let us see if we can find some direction of demand from these DSPs.

ADSP-21060LCW-160

Figure2-ADSP-21060LCW-160

ADSP-21060LCW-160 is ADI's SHARC series processor. It supports IEEE-compatible 32-bit floating point, 40-bit floating point, and 32-bit fixed-point mathematical operations. The peak floating point operation performance is 120MFLOP. It is the SHARC series for high-performance digital signal processing. Application-optimized 32-bit processor. ADSP-2106x is based on the ADSP-21000 processor core and is a complete system-on-chip. Compared with the latter, the highlight is the addition of 4Mb on-chip dual-port SRAM and integrated I/O peripherals supported by a dedicated I/O bus.

ADSP-21060LCW-160 has been a hot part for a long time. It was popular in the first half of last year, and its price has been above 10,000 yuan for a long time. After the holidays, the search volume for this material quickly picked up, reaching more than 1,000 times in a single week. Although it is not as popular as in the past, the rapid recovery is worth noting. The domestic inventory index of this material has been low for a long time, which means that its market circulation is small, so the price of over 10,000 yuan is understandable. In addition, the part was listed as "not recommended for new designs" by the original manufacturer and has entered the end of its life cycle, which also contributes to its high price.

DSPB56367AG150

DSPB56367AG150 can be traced back to the era of Freescale. It is a 24-bit DSP. The target application is audio processing. Its computing power reaches 150MIPS. It is currently listed by NXP as not recommended for new designs. Earlier, the material's popularity was the highest in the third quarter of last year. This round of popularity began to emerge after the holidays and reached its peak in early March, with the price at a relatively high level of around 145 yuan.

DSPIC30F2010-30I/SP

Figure4-DSPIC30F2010-30I/SP

Microchip defines DSPIC30F2010-30I/SP as a "high-performance 16-bit DSC". Compared with DSP, the difference between DSC and DSC lies in the difference between processor (Processor) and controller (Controller). As a DSC defined by the original factory, the 30MIPS computing power that this material can achieve is much lower than that of ordinary DSPs, and the built-in storage capacity is also lower. Compared with DSP, which focuses on digital signal processing, DSC focuses on control aspects, such as motor driving, so the computing power requirements are reduced.

The search volume of DSPIC30F2010-30I/SP increased rapidly in the month after the holiday, reaching more than 2,000 searches in a recent week, compared with the previous monthly peak of only more than 1,000 searches. Its domestic inventory data has also risen in step with search volume, indicating strong current demand.

Conclusion

The above three hotspot DSPs of the ADI, Microchip, and NXP brands are very representative, two of which are "not recommended for new designs." The life cycle is coming to an end, triggering the need for stocking up. In addition to these, there are some popular DSPs recently, and some models with very low search volume have increased in popularity recently. Judging from the latest "Daily Comprehensive Index" of the Chuangxin Index, there are many DSPs. The phenomenon of a sudden surge in popularity and then a return to silence in the short term indicates that there seems to be some temporary demand.

So where is the demand for DSP today? One possible approach is AI-related applications, such as the cultivation of production-type AI algorithms, which require the input of a large amount of corpus or image data. For the initial processing of this information, DSP must be introduced. The high-performance DSP can perform floating-point operations and can be well-matched with GPU, NPU, ASIC, etc. as the main chip to assist the system to achieve maximum performance. The name DSP means that it is best at digital signal processing tasks, which distinguishes it from MCU, SoC, etc., which are also main chips.
