Скачать или смотреть Computer Memory Organization and Cache Mapping

Computer memory and organization, emphasizing the central role of memory in the Von Neumann architecture. The video first explores various types of memory, distinguishing between volatile (RAM, including DRAM and SRAM) and non-volatile (ROM and its variations like EPROM and flash memory) types. A significant portion of the lecture is dedicated to explaining the memory hierarchy, clarifying how different memory speeds and costs lead to a tiered system involving registers, cache, main memory, and secondary storage, along with concepts like hit rate and locality of reference. Finally, the video offers a thorough presentation of cache memory and the three primary cache mapping schemes: direct mapping, fully associative mapping, and set-associative mapping, illustrating how each scheme converts a main memory address into a cache location.
