Masters request access to a shared resource, such as a shared bus. Usage of the shared bus by each of the masters is monitored, a request to use the shared bus by one of the masters is received, and usage of the shared bus by the master is compared with a corresponding bandwidth threshold. The request is arbitrated if the usage of the shared bus by the master is below the bandwidth threshold, and the request to use the shared bus is granted to the master based on the arbitration.

Shared resource arbitration

A high-speed programmable serial port having a finite state machine, a clock generator capable of controlling shifting of bits from a shift register and a shift register having a bit counter capable of maintaining a numbered count of data bits in a serial output. The clock generator and shift register reduce the burdens on a finite state machine, thus improving data throughput and the ability to provided data according to a multitude of data protocols.
