Superscalar 32-bit Processor

Overview

N15/N15F are dual-issue superscalar AndesCore™ processors capable of delivering performance at 5.41 CoreMark/MHz, the highest among the same level products in the industry. N15/N15F comes with a variety of configuration options, including MMU, cache and local memory. The 64-bit data buses for caches, local memory and the main bus provide the bandwidth needed for instruction fetch and data access. N15F includes a built-in IEEE-754 compliant floating point unit that enhances the floating point processing capability. N15/N15F is designed for diversified performance-driven applications on the embedded Linux, Real-Time OS or bare metal environment.
