WebWith tf.data, you can do this with a simple call to dataset.prefetch (1) at the end of the pipeline (after batching). This will always prefetch one batch of data and make sure that there is always one ready. dataset = dataset.batch(64) dataset = dataset.prefetch(1) In some cases, it can be useful to prefetch more than one batch. WebA 4n prefetch buffer would accomplish this exactly ("n" refers to the IO width of the memory chip; it is multiplied by the burst depth "4" to give the size in bits of the full burst sequence). An 8n prefetch buffer on a 8 bit wide DRAM would also accomplish a 64 bit transfer.
