LPDDR3 DRAM in AI image-processing SoC

Beijing, China-based Tsing Micro’s TX510 SoC is a highly advanced AI edge computing engine optimized for functions such as 3D sensing, face recognition, object recognition and gesture recognition.

Paired with Winbond’s LPDDR3 DRAM, which offers maximum bandwidth of 1866Mb/s and operates from a dual 1.2V/1.8V supply with power-saving features such as Deep Power-Down mode and a Clock Stop capability, the TX510 offers outstanding speed and accuracy in AI imaging applications.

Tsing Micro has implemented an innovative architecture in the TX510 SoC: it includes a 32-bit RISC processor, a reconfigurable neural network engine, a reconfigurable general computing engine, an image signal processor and a 3D sensing engine. For shipping to customers, the TX510 is combined with Winbond’s 1Gb LPDDR3 DRAM die in a single 14x14mm TFBGA System-in-Package (SiP).

Achieving computing throughput of up to 1.2 TOPS (tera operations per second), this SiP can perform accurate face recognition (false acceptance ratio of one in ten million) in less than 100ms, and compare features with a library of 100,000 faces in less than 50ms. Peak operating power consumption is just 450mW, and the chip uses just 0.01mW in quiescent mode.

The TX510 is intended for use in applications which require high-speed image detection and recognition, including biometric sensing, video surveillance, smart retail operations, smart home automation and advanced industrial automation.

Wang Bo, CEO of Tsing Micro, said: “Evaluation of the Winbond LPDDR3 DRAM shows that it is highly competitive both in terms of speed and power consumption. But equally important to us when developing the TX510 was the support and expertise that Winbond provided to us in integrating the DRAM die into a SiP in such a way that it maintained high performance and high signal integrity while taking care of thermal management.”

“Winbond is fast gaining a reputation for providing excellent support to chip and SoC manufacturers which are developing leading-edge AI products. With Winbond low-power DRAM inside, AI products such as the TX510 can set new benchmarks for high performance and throughput while operating from a limited battery power supply,” added Winbond.
