Four-core CPU architecture with independent instruction and data caches per core, unified L2 cache, and memory management unit for virtual-to-physical address translation. Each core contains registers, ALU, and barrel shifter, with instruction and data flows managed through a centralized core controller and control unit. The MMU sits between the L2 cache and RAM, enabling protected memory access and address translation across all four cores. This design demonstrates cache hierarchy optimization and memory protection essential for modern multi-core processors.
