Automotive To support the doubling of bandwidth to 64 GT/s, PCIe 6.0 technology uses PAM4 modulation, which enables it to run 2 bits/cycle compared to the 1 bit/cycle with the previous NRZ modulation. To compensate for the higher BER (Bit Error Rate), XpressRICH for PCIe 6.0 architecture implements FEC (Forward Error Correction) combined with CRC (Cyclic Redundancy Check). XpressRICH for PCIe 6.0 architecture also supports the new L0p low power mode, enabling traffic to be transmitted on a reduced set of lanes, reducing power consumption without impacting traffic flow. To support configurabil...

Abstract In this paper, multi-antenna transceiver for zero-padded orthogonal frequency division multiplexing (OFDM) system is designed at mmWave by integrating full-duplex unmanned aerial vehicle (UAV) into the terrestrial cellular networks. Assuming that there exist no direct communication links between the ground base station (GBS) and the mobile users due to unexpected blockages from high storied buildings in urban area, the UAV applies decode-and-forward cooperative strategy on the received OFDM signals transmitted from GBS and re-transmits to the ground mobile users and passive eavesdrop...

Increasing bandwidth to 128 GB/s with a tailored PCIe 6.0 IP Controller By Romain Tourneau, PLDA While the PCIe 6.0 specification is expected to be finalized and released later in 2021, PLDA has been hard at work to address the needs of early adopters looking for the most advanced PCIe 6.0 IP solution for their SoCs and ASICs. Although PCIe 5.0-enabled systems are not yet available in the general market, Automotive, AI and IoT system designers are already pushing for more bandwidth than 5.0 supports. Self-driving cars are the perfect example of this need -- to continuously sense and react to ...

By Shine Chung, Chairman of Attopsemi™ Technology Abstract: OTP stands for “One-Time Programmable”, a device that can only be programmed once to store data permanently but ideally read infinite times. Traditionally, testability has been an issue for OTP. Every OTP bit should be programmed to ensure programmability. However, if only a single bit is programmed, the OTP block can no longer be used. Patented by Attopsemi™, I-fuse™ is a revolutionary non-breaking fuse technology that can be reliably programmed by heat assisted electromigration below a break point. Any cell can be tested...
