TDM Frame Transmission Using Ring Buffer Descriptors

The patent segments the buffer management into multiple small fixed-size buffers organized in a ring structure, rather than using one or two large ping-pong buffers. This segmentation allows data to be distributed across multiple smaller buffers, reducing the time any single buffer needs to be filled and transmitted, thereby reducing overall transmission delay while maintaining reliable data transfer through the ring buffer mechanism.

The patent implements preliminary action by pre-allocating multiple fixed-size buffers in a ring structure and pre-establishing the buffer management mechanism with head and tail pointers. This preliminary setup eliminates the need for dynamic buffer allocation and management during data transmission, reducing processing delay and enabling immediate data transmission without buffer setup overhead.

The patent extracts and removes the invalid data transmission requirement by using fixed-size buffers where the buffer boundaries are clearly defined. The tail pointer indicates exactly where valid data ends, eliminating the need to transmit padding or invalid data that would otherwise be required with variable-size buffers. This extraction principle directly reduces link resource wastage.

The patent changes the buffer size parameter from variable (in traditional ping-pong buffers) to fixed. This parameter change allows the system to optimize buffer sizes to match actual data transmission needs, preventing the transmission of excessive invalid data and reducing link resource consumption while maintaining adequate data transmission capacity.

The patent implements continuity of useful action through the ring buffer structure where multiple buffers can be filled and transmitted in continuous sequence without idle periods. While one buffer is being transmitted, another can be filled, ensuring continuous data flow and eliminating the idle time that occurs in traditional ping-pong buffer modes when buffers need to be swapped or refilled. This continuous operation improves real-time processing capability and reduces bus bandwidth load.

The patent introduces dynamics through the ring buffer management mechanism with head and tail pointers that dynamically track the state of data in the buffer ring. This dynamic management allows the system to adapt to varying data arrival patterns and transmission rates, enabling efficient real-time processing by always knowing which buffers contain valid data ready for transmission, thus improving productivity while reducing operational complexity.
