Increased efficiency of data payloads to data arrays accessed through registers in a distributed virtual bridge
View Patent ↗A system and method for efficient transfer of data from a controlling bridge to a register of a distributed bridge element. A Load Store over Ethernet (LSoE) frame processing engine (FPE) is equipped with a repeat and a repeat with strobe function that, when coupled with an auto-increment function of an indirect register facility, allows a distributed virtual bridge to move data payload more efficiently which decreases the data loading on the computers data paths used for other data transfers.
1. A method for communicating data with a frame processing engine using a repeat function to move a data payload more efficiently over a network comprising:
receiving a request frame having a plurality of control blocks wherein a single control block of the plurality of control blocks indicates a repeat function that instructs the frame processing engine to read a plurality of data blocks;
writing a command to an array control register to set up communication to access a first data row in a partition array and enable an auto-increment function; and
in response to the single control block with the repeat function, repeatedly reading an array data register to read the plurality of data blocks indirectly through the array data register from an array in a data partition and placing the plurality of data blocks in a response frame.
2. The method of claim 1 further comprising:
writing the control register to disable auto-increment;
reading the final data block from the data register; and
returning the response frame with data read from the plurality of data blocks.
3. The method of claim 1 further comprising:
writing a command to an array control register to set up communication to access a plurality of data registers to read a plurality of data blocks in the partition array and to enable an auto-increment function; and
in response to a second single control block having a repeat function with strobe, repeatedly reading a plurality of array data registers to read the plurality of data blocks indirectly through the array data registers from the array in the data partition.
4. The method of claim 3 further comprising:
writing the control register to disable auto-increment;
reading the final data blocks from the plurality of data registers; and
returning the response frame with data read from the plurality of data blocks.
5. The method of claim 3 wherein the repeat function with strobe uses a single control block to write a plurality of data blocks indirectly through a plurality of data registers to read to the array in the data partition.
6. The method of claim 1 wherein the frame is a load store over Ethernet (LSoE) frame and the network is an Ethernet network.
7. The method of claim 1 wherein the repeat function uses a single control block to write a plurality of data blocks indirectly through the array data register to the array in the data partition.
8. A method for communicating data with a frame processing engine using a repeat function to move a data payload more efficiently over a network comprising:
receiving a load store over Ethernet (LSoE) request frame having a plurality of control blocks wherein a single control block of the plurality of control blocks indicates a repeat function that instructs the frame processing engine to read 178 data blocks;
writing a command to an array control register to set up communication to access a first data row in a partition array and enable an auto-increment function;
in response to the single control block with the repeat function, repeatedly reading an array data register to read the plurality of data blocks indirectly through the array data register from an array in a data partition and placing the plurality of data blocks in a response frame;
writing the control register to disable auto-increment;
reading the final data blocks from the plurality of data registers; and
returning the response frame with data read from the plurality of data blocks.
