System and method for data transfer between buses having different speeds

A method for transferring data between a first bus with a first clock rate and a second bus with a second clock rate, the method comprising the steps of:

• writing data from the first bus to a newly selected storage device from a first set of storage devices each clock cycle of the first bus;
• setting a flag when data is placed in a threshold storage device in the first set of storage devices;
• and
• after the flag is set to a predetermined value, reading the data from the first set of storage devices into the second bus at the second clock rate;
• wherein a bandwidth of the second bus is greater than a bandwidth of the first bus.

A system for transferring data between buses, the system comprising:

• a first bus having a first clock rate and a first bus width;
• a second bus having a second clock rate and a second bus width;
• a first set of storage devices having a plurality of storage devices wherein each storage device has a width;
• a second set of storage devices coupled to the first set of storage devices for transferring data, the second set of storage devices having at least one storage device wherein each storage device has a width and wherein the width of each storage device of the second set of storage devices is at least twice the width of each storage device of the first set of storage devices;
• a first multiplexor coupling the first bus with the first set of storage devices;
• and
• a second multiplexor coupling the second bus with the second set of storage devices;
• wherein a bandwidth of the first bus is less than a bandwidth of the second bus.

A method for transferring data between a first bus and a second bus wherein the first bus has a first clock rate and the second bus has a second clock rate, wherein the first clock rate is greater than the second clock rate, the method comprising:

• writing a first set of storage devices with data from the first bus;
• filling a second set of storage devices with data from the first bus at the first clock rate when the first set of storage devices are filled to a preset point;
• and
• transmitting the data at the second clock rate from the second set of storage devices to the second bus as the first set of storage devices are being filled;
• wherein a bandwidth of the second bus is greater than a bandwidth of the first bus.

A system for transferring data between a first bus having a width and a clock rate and a second bus having a width and a clock rate, wherein the clock rate of the first bus is greater than the clock rate of the second bus, the system comprising:

• a first set of storage devices, composed of a plurality of storage devices;
• a first multiplexor responsive to a control signal for creating a path between the first bus and one of the storage devices from the first set of storage devices;
• a first bus control logic sending a control signal to the first multiplexor at the clock rate of the first bus;
• a second set of storage devices, composed of one or more storage devices;
• a second multiplexor responsive to a control signal for creating a path between one of the storage devices from the second set of storage devices and the second bus;
• and
• a second bus control logic sending a control signal to the second multiplexor at the clock rate of the second bus.

A system for transferring data between a first bus with a first clock rate and a second bus with a second clock rate, the system comprising:

• means for writing data from the first bus to the newly selected storage device from a first set of storage devices each clock cycle of the first bus;
• means for setting a flag when data is placed in a threshold storage device in the first set of storage devices;
• and
• means for reading from the first set of storage devices onto the second bus at the second clock rate after the flag is set to a predetermined value.
