PCIe Byte Enable Decoder
- ENTITY PCIE_BYTE_EN_DECODER IS
This component decodes Last and First Byte Enable signals for the incoming PCI Express transactions. Non-continuous series of ones are replaced by contiuous. For example:
Input (Last_BE,First_BE) -> Output (Last_BE,First_BE)
(0010, 0101) -> (0011,1111)
(1111, 0101) -> (1111,1111)
(0000,0100) -> (0000,0100)
(0111,0100) -> (0111,1100)
(1000,0001) -> (1111,1111)
(0000,0110) -> (0000,0110)
