23.5. Programming with the Intel FPGA Avalon FIFO Memory
This section describes the low-level software constructs for manipulating the Intel FPGA Avalon FIFO memory core hardware. The table below lists all of the available functions.
Function Name | Description |
---|---|
altera_avalon_fifo_init() | Initializes the FIFO. |
altera_avalon_fifo_read_status() | Returns the integer value of the specified bit of the status register. To read all of the bits at once, use the ALTERA_AVALON_FIFO_STATUS_ALL mask. |
altera_avalon_fifo_read_ienable() | Returns the value of the specified bit of the interrupt enable register. To read all of the bits at once, use the ALTERA_AVALON_FIFO_EVENT_ALL mask. |
altera_avalon_fifo_read_almostfull() | Returns the value of the almostfull register. |
altera_avalon_fifo_read_almostempty() | Returns the value of the almostempty register. |
altera_avalon_fifo_read_event() | Returns the value of the specified bit of the event register. All of the event bits can be read at once by using the ALTERA_AVALON_FIFO_STATUS_ALL mask. |
altera_avalon_fifo_read_level() | Returns the fill level of the FIFO. |
altera_avalon_fifo_clear_event() | Clears the specified bits and the event register and performs error checking. |
altera_avalon_fifo_write_ienable() | Writes the specified bits of the interruptenable register and performs error checking. |
altera_avalon_fifo_write_almostfull() | Writes the specified value to the almostfull register and performs error checking. |
altera_avalon_fifo_write_almostempty() | Writes the specified value to the almostempty register and performs error checking. |
altera_avalon_fifo_write_fifo() | Writes the specified data to the write_address. |
altera_avalon_fifo_write_other_info() | Writes the packet status information to the write_address. Only valid when the Enable packet data option is turned on. |
altera_avalon_fifo_read_fifo() | Reads data from the specified read_address. |
altera_avalon_fifo_read__other_info() | Reads the packet status information from the specified read_address. Only valid when the Enable packet data option is turned on. |
