Abstract: An ethernet controller for controlling the transmission of data between a station and an ethernet having four FIFOs for managing the transmission of data between the station CPU, a memory buffer, and the ethernet. The four FIFOs each have a selected size to maximize performance of the controller. The controller includes a arbiter to arbitrate which pending request from each of the FIFOs will have priority. The controller limits the transmission of data by each FIFO to 32 bytes per grant. Each FIFO includes logic to convert data in a first bit size format to a second bit size format. The controller also includes logic to convert a 16 bit address to two 8 bit portions for transmission over an 8 bit address bus and logic to reformat the two 8 bit portions to the 16 bit address.

Abstract translation: 一个以太网控制器，用于控制站和具有四个FIFO的以太网之间的数据传输，用于管理站CPU，存储器缓冲区和以太网之间的数据传输。 四个FIFO都具有选定的大小以最大化控制器的性能。 控制器包括仲裁器，用于仲裁来自每个FIFO的待决请求将具有优先级。 控制器将每个FIFO的数据传输限制为每个授权32个字节。 每个FIFO包括将第一位大小格式的数据转换为第二位大小格式的逻辑。 控制器还包括将16位地址转换为两个8位部分以用于通过8位地址总线传输的逻辑，以及将两个8位部分重新格式化为16位地址的逻辑。
