The hottest Xianglong I emphasizes flexibility and

"Xianglong I" emphasizes flexibility and desalinates processing speed

more and more Chinese IC enterprises have joined the ranks of CPU chip development. After ark processor and Godson processor, Shenzhen Yanxiang Intelligent Technology Co., Ltd. (hereinafter referred to as "Yanxiang") has launched a 32-bit embedded processor named "Hero-I", and positioned its target market at information terminals and industrial applications

Zhu Jun, research and development director of Yanxiang, said, "Yanxiang is a supplier of platform products, which requires different CPU chips when making various industry platforms. In the past, it was mainly developed based on Intel and national semiconductor processors, but with the continuous subdivision of industry applications, there is now C performance: tensile test (stress-strain test) Generally, the two ends of the material sample are clamped on two fixtures with a certain distance between them. Pu can not meet all needs. Xianglong I came out under this background. Yanxiang will develop industrial terminal application solutions based on Xianglong processor and integrate CPU into Yanxiang's existing platform products. "

unlike some Chinese enterprises that emphasize completely independent development, Yanxiang does not pursue complete independence in intellectual property rights, but adopts a very mature 32-bit ARM7TDMI core. Since the ARM7 core was launched by arm company a few years ago, its performance is not very powerful, and its core operating frequency is 66MHz. Last year, the RISC processor launched by ark technology reached 400MHz

"with the gradual development of the embedded market, the characteristics of small batch and multiple varieties become more prominent. In this part of the market, there is a cost problem in using all the existing CPUs. Although using FPGA can meet some markets, it is unrealistic to use all of them." Ma Linke, deputy chief engineer of Yanxiang, said, "our processors are mainly customized for related applications, and we don't pay attention to how high the speed is, but emphasize the flexibility of products. For this reason, Yanxiang adopts the design idea of FPGA + SOC."

in fact, products with similar ideas are not uncommon. FPGA manufacturers mainly provide such products, and the design of FPGA + CPU core has begun to enter the relevant market. Xilinx, Altera and other manufacturers mainly want to realize system functions on FPGA and have better flexibility at the same time. Compared with Yanxiang Xianglong I, FPGA manufacturers' products have many advantages in product line, application scope and performance. In this regard, Yanxiang Malinke pointed out that Yanxiang Xianglong I is not a pure FPGA technology, but uses SRAM technology to realize programmable functions

after arm enters China, the long-term development strategy, including the University plan, will enable ARM processors to be widely used in China. Moreover, SOC products with arm chips have not entered the market in a real sense, or users cannot effectively expand arm chips. Xianglong I adopts technology different from traditional SOC and has advantages in architecture. System design manufacturers can design multiple products for different markets on one platform

in terms of product planning, according to the idea of adding more peripheral modules to CPU, Yanxiang has launched 40000 and 200000 FPGA processor products with two capacities respectively. The former is suitable for the market where the system does not require much expansion function, while the latter mainly faces the market where the expansion unit requires more. These two chips have been successfully put into production and can be ordered in small quantities

according to the introduction, Xianglong I integrates a large number of functions required by the system, and supports UART (full function or non full function), SPI (master/slave), I2C (master/slave), can, PS2, I2S (master/slave), counter, multiplier, data register and shift register on configurable modules, all of which are indicative memories of the resistance of metals to micro or small amount of plastic deformation, dual port RAM, asynchronous transceiver FIFOs, r/a transceiver FIFOs 7-segment nixie tube driver, character/Graphic LCD controller, RGB interface, VGA interface, status register, pulse width regulator, single and bidirectional i/o port, three state output port, mailbox interface, tripledes, singledesecb, singledescbc, etc

these configurable unit libraries such as LCD controller, serial port, encryption/decryption algorithm, etc. will be provided to customers free of charge. While enriching the unit library, Yanxiang will also expand the chip functions, such as adding one or two 10/100M Macs according to the network requirements of embedded products; To sum up, some card readers may also be integrated. In addition, special SOC will be customized for some industries, such as tax trapezoidal screw control

"In terms of market planning, Yanxiang believes that as an embedded platform supplier, its products are no longer limited to the control field. Xianglong I will enter new markets, including terminal applications. In the future, Yanxiang may improve some functions and make products dedicated to certain industries. Now Yanxiang is committed to developing platform solutions on Xianglong I, and then pushing these solutions to the market. In the future, it is also possible to sell Xianglong I directly to the market Processor. " Zhu Jun said

however, he also pointed out that embedded manufacturers are more accustomed to finding the corresponding processors according to their needs. In the future, manufacturers can design the required products according to the platform of Evonik. It is difficult for the industry to be very familiar with FPGA + SOC chips in a short time, but it is hoped that the market will reach about 100000 chips in the next year. "It is expected that the market will be on track in the middle of next year and the market will grow." He added
