Although these include no spinning magnetic media, processor performance requirements are equally challenging for SSDs. There is an approach of using multiple processors, splitting the tasks of managing data read and writes along with wear leveling algorithms (ensuring different areas of the flash are written to, in order to prolong the useful life of the disk).
OEMs value the unparalleled software tools and debug infrastructure around the ARM architecture that allows them to rapidly evolve and deploy products from generation to generation. The Cortex-R4 processor architecture features the appropriate balance between processor performance, and real-time response times, with a high degree of debugability to support the AMP chip architectures appearing now to address this market.
ARM Physical IP libraries and Power Management Kits are designed to reduce cost and power usage by minimizing silicon area and leakage, while optimizing performance ensure that the overall device minimizes power leakage. In addition, Physical IP Embedded Memory create high density on-chip memories on a SoC that can exceed 4Mbyte today. The resultant memories, optimized for both performance and power, offering fault tolerance to increase manufacturing yields. Physical IP DDR PHY enables robust off-chip memory interface performance at high clock-speed and low power.
