Lane Management
https://www.rambus.com/chip-interface-ip-glossary/lane-management/Lane Management refers to the dynamic control and optimization of data lanes in high-speed serial communication protocols such as PCI Express (PCIe), Compute Express Link (CXL), and Serial ATA (SATA). A “lane” is a pair of differential signal wires used to transmit data in one direction. Lane management ensures efficient use of these lanes by handling lane negotiation, aggregation, error recovery, and power control, which are critical for maintaining performance and reliability in multi-lane systems.
FEC (Forward Error Correction)
https://www.rambus.com/chip-interface-ip-glossary/fec/Forward Error Correction (FEC) is a method used in digital communication systems to detect and correct errors in transmitted data without requiring retransmission. It works by adding redundant bits, known as error-correcting codes, to the original data stream. These codes allow the receiver to identify and fix errors caused by noise, interference, or signal degradation during transmission.
In-line ECC (Error Correction Code)
https://www.rambus.com/chip-interface-ip-glossary/in-line-ecc/In-line ECC is a hardware-based error correction mechanism that integrates error detection and correction directly into the data path of memory or data transmission systems. Unlike traditional ECC, which may require separate memory or processing steps, in-line ECC operates transparently and in real time, embedding parity or redundant bits alongside the data as it moves through the system. This approach is essential for high-speed, high-reliability applications such as data centers, AI accelerators, and automotive systems.
HPC (High-Performance Computing)
https://www.rambus.com/chip-interface-ip-glossary/hpc/High-Performance Computing (HPC) refers to the use of supercomputers and parallel processing techniques to solve complex computational problems at high speed and scale. HPC systems aggregate computing power from thousands of processors or nodes to perform trillions of calculations per second, enabling breakthroughs in fields such as climate modeling, genomics, financial simulations, and artificial intelligence.
DMA Engine
https://www.rambus.com/chip-interface-ip-glossary/dma-engine/A DMA Engine (Direct Memory Access Engine) is a hardware subsystem that enables peripherals or processors to transfer data directly to or from memory without involving the CPU. This offloads data movement tasks from the processor, improving system performance and efficiency, especially in high-throughput applications like networking, storage, and graphics.
Display Stream Compression (DSC)
https://www.rambus.com/chip-interface-ip-glossary/dsc/Display Stream Compression (DSC) is a visually lossless compression standard developed by the Video Electronics Standards Association (VESA) to reduce the bandwidth required for transmitting high-resolution video streams over display interfaces like DisplayPort, HDMI, and MIPI DSI/DSI-2. DSC enables the delivery of ultra-high-definition (UHD) content—including 4K, 8K, and beyond—without compromising image quality or requiring excessive data rates.
Memory Test Analyzer
https://www.rambus.com/chip-interface-ip-glossary/memory-test-analyzer/A Memory Test Analyzer is a diagnostic tool or software module used to evaluate the performance, reliability, and integrity of memory subsystems in computing environments. It systematically tests memory components, such as DRAM, SRAM, or flash, for faults, timing issues, and data retention problems. These analyzers are essential in both development and production environments to ensure memory modules meet performance and quality standards.
Lossless Compression
https://www.rambus.com/chip-interface-ip-glossary/lossless-compression/Lossless compression is a data encoding technique that reduces file size without losing any original information. Unlike lossy compression, which discards data to achieve smaller sizes, lossless methods preserve every bit of the original content, allowing perfect reconstruction upon decompression. This is essential in applications where data integrity is critical, such as executable files, text documents, medical imaging, and scientific data.
Lane Operation
https://www.rambus.com/chip-interface-ip-glossary/lane-operation/Lane Operation refers to the management and coordination of individual data transmission lanes within high-speed serial interfaces such as PCI Express (PCIe), Compute Express Link (CXL), and Serial ATA (SATA). A lane consists of a pair of differential signal wires, one for transmitting and one for receiving data. Lane operation ensures that each lane functions optimally, supporting scalable bandwidth, reliable data transfer, and efficient power usage across multi-lane configurations.
Interconnect
https://www.rambus.com/chip-interface-ip-glossary/interconnect/An interconnect is the communication infrastructure that links various components within a computing system, such as processors, memory, accelerators, and I/O devices, to enable data exchange. It can be implemented as on-chip buses, high-speed serial links, or network fabrics, depending on the system architecture. Interconnects are foundational to performance, scalability, and efficiency in systems ranging from embedded devices to data centers and high-performance computing (HPC).
