Intel's R&D team in Haifa, Israel designed the Core microarchitecture. As early as 2003, the Israeli team was famous for designing Banias processors with high performance and low power consumption. Core microarchitecture is their latest masterpiece after Yonah microarchitecture. Core microarchitecture has existed in Intel's plan for a long time. As early as the summer of 2003, Intel vaguely mentioned that it was originally the processor used by the third generation Napa platform and the fourth generation Santa Rosa platform of Centrino platform. Unexpectedly, due to the failure of NetBurst microarchitecture, the core microarchitecture was changed by Intel, and it was given the historical mission of replacing NetBurst microarchitecture and unifying desktop, mobile and server platforms. Intel's new kernel has many names. At the beginning of the design, the Israeli team adopted Merom as the development code. Merom originally meant a lake near the Jordan River, which is also an interesting habit of Intel-using the place name near the residence of the R&D team as the product development code. Then, when Intel began to promote microarchitecture on a large scale in 2005, it was described as "Next Generation Microarchitecture" (NGMA for short). At IDF conference in 2006, Intel officially declared it as "core micro-architecture".
