Abstract
Systems, apparatuses, and methods for dynamic buffer management in multi-client token flow control routers are disclosed. A system includes at least one or more processing units, a memory, and a communication fabric with a plurality of routers coupled to the processing unit(s) and the memory. A router servicing multiple active clients allocates a first number of tokens to each active client. The first number of tokens is less than a second number of tokens needed to saturate the bandwidth of each client to the router. The router also allocates a third number of tokens to a free pool, with tokens from the free pool being dynamically allocated to different clients. The third number of tokens is equal to the difference between the second number of tokens and the first number of tokens. An advantage of this approach is reducing the amount of buffer space needed at the router.
