What DDR is

DDR SDRAM is the mainstream dynamic memory architecture for PCs, workstations, and servers. “Double Data Rate” means data transfers occur on both clock edges, doubling throughput without raising the clock frequency. DDR comes in generations (DDR → DDR2 → DDR3 → DDR4 → DDR5) that increase bandwidth, improve efficiency/reliability,

GPMI (General-Purpose Media Interface) is a NAND-flash controller IP block found in several NXP/Freescale i.MX application processors (e.g., i.MX23/i.MX28/i.MX6 variants). It offloads low-level NAND signaling, integrates tightly with a hardware BCH error-correction engine, and streams data through a DMA engine to system… Read More

Semiconductor Verification IP (VIP) is a pre-verified, reusable block of code or models used in simulation and verification environments to validate the correctness and interoperability of semiconductor designs. VIPs emulate the behavior of industry-standard protocols, interfaces, or system components, allowing verification… Read More
