ADDRESS GENERATION AND DATA PATH CONTROL TO AND FROM MULTI-TRANSMITTING PACKET

摘要

PURPOSE: An ethernet controller is provided to generate an address by efficiently converting 16-bit data into 32-bit data and control various write/read functions controlled by an ethernet. CONSTITUTION: The controller comprises a memory, a first FIFO(first-in, first-out) for managing transmission of CPU(central processing unit) data in a CPU, a second FIFO for managing transmission of the CPU data from the memory to an ethernet, and an arbiter for controlling the first and the second FIFOs. The controller controls data transmission between a station having the CPU and the ethernet.
