Fly-by support module for a peripheral bus

A method of performing a fly-by write operation on a peripheral bus, the method comprising:

• providing an activated fly-by write enable signal from a master device to a fly-by slave interface;
• providing read addresses from the master device to a slave device on the peripheral bus;
• retrieving fly-by write data values from the slave device in response to the read addresses;
• providing the fly-by write data values from the slave device to the peripheral bus;
• activating a ready signal on the peripheral bus with the slave device, wherein the ready signal is activated on the peripheral bus when the slave device provides a fly-by write data value to the peripheral bus;
• retrieving the fly-by write data values from the peripheral bus with the fly-by slave interface in response to the activated fly-by write enable signal and the activated ready signal;
• and
• providing the fly-by write data values from the fly-by slave interface to a peripheral device.

A method of performing a fly-by read operation on a peripheral bus, the method comprising

• providing an activated fly-by read enable signal from a master device to a fly-by slave interface;
• providing fly-by read data values from a peripheral device to the fly-by slave interface;
• providing write addresses from the master device to a slave device on the peripheral bus;
• activating a ready signal on the peripheral bus with the slave device, wherein the ready signal is activated on the peripheral bus when the slave device has received a fly-by read data value from the peripheral bus;
• providing the fly-by read data values from the fly-by slave interface to the peripheral bus in response to the activated ready signal;
• and
• writing the fly-by read data values on the peripheral bus to the slave device at addresses corresponding to the write addresses.
