➀ The PCI-SIG has released version 0.7 of the PCIe 7.0 specifications for member approval; ➁ PCIe 7.0 will double the bandwidth of PCIe 6.0, offering 128GT/s and 512GB/s bi-directionally on an x16 connection; ➂ PCIe 7.0 will use PAM4 signaling, improve power efficiency, and maintain backward compatibility.

➀ Researchers at the Fraunhofer Institute for Photonic Microsystems (IPMS) have developed a new LCOS microdisplay with a high-speed CMOS backplane; ➁ The display achieves data transfer speeds of up to 576Gbit/s and is designed for applications in AR/VR, optogenetics, and quantum computing; ➂ The technology is set to launch commercially in 2026.

Researchers have developed an artificial nose with a single sensor capable of distinguishing volatile organic compounds with 96% accuracy. The technology uses a graphene oxide and Nafion-coated antenna that operates across a frequency range of 1 to 8GHz, offering dual functionality for data transfer over the 5.8GHz ISM band. The team envisions medical applications, similar to trained dogs detecting diseases through volatile organic compounds.

➀ Tags in PCIe TLPs are identifiers for non-posted requests, ensuring consistency between requests and completions. ➁ As PCIe speeds increase, tag size has expanded from 8-bit to 14-bit to optimize performance. ➂ PCIe 6.0 mandates specific tag size capabilities for functions operating at higher speeds. ➃ Configuration registers for tag sizes are detailed, with 14-bit tags having unique settings in the Device 3 Extended Capability Structure. ➄ Combinations of tag size enablement determine the maximum tag size and permissible tag value ranges.

1. Silicon photonics merges optics with silicon to enable data transfer at the speed of light. 2. This technology originated in the 1980s and is crucial in microelectronics. 3. It provides faster data transfer rates and lower power consumption than electronic-only systems.
