Abstract
Integrated circuits are disclosed which implement multiple channel media access control devices for controlling network communications. The integrated circuits include multiple channel slices which output data for transmission through the network. Each of the channel data are input to a single data memory, which reduces the size of the integrated circuit. Since only one data memory is used to buffer data from multiple channels, the data are first retimed from individual media access control circuit clock domains to a common host clock domain and then scheduled for output to the host. By retiming the data, integrated circuit signal throughput is enhanced. Deeply embedded transmit and receive FIFOs are provided to receive the channel data and implement shared memory access.
