This thesis presents a behavioral model for dynamic virtual First-In-First-Out (FIFO) buffers within a descriptor-based memory system architecture, designed to support efficient context switching and preemption in high-performance hardware environments. The hardware module manages a shared pool of register buffers across multiple virtual FIFOs each representing either a cluster (processing destination) or a heap (free buffer pool) using descriptor RAM to dynamically link and organize buffer allocations. Clusters are the destinations where incoming transactions are processed. To enable efficient dispatching, the system implements a “Serial In, Parallel Out” behavior: transactions arriving from a single input are dynamically divided and routed to different clusters.
