Abstract
Techniques for transmitting and receiving FIFO status signals on a hard intellectual property (HIP) block of a programmable logic integrated circuit are provided. The FIFO status signals are demultiplexed after being received in the HIP block and then stored in a per port context. The FIFO status signals are retrieved from a storage block in a per port context and transmitted out of the HIP block through a multiplexer. The demultiplexing and multiplexing reduces the number of input and output ports that are needed to transmit the status signals into and out of the HIP block, yet providing the necessary status throughput for a full-rate SPI4.2 status channel implementation.
