+# The DPU application reads BL<<2 sized blocks of data from MRAM to WRAM via
+# DMA (mram_read). It then performs the specified type of copy operation
+# (i.e., streaming copy / strided copy / copy of random elements) within this
+# block and writes the result back from WRAM to MRAM via DMA (mram_write).
+# By default (MEM=WRAM), each tasklet reports the total number of cycles
+# spent in the WRAM-to-WRAM copy operation. With MEM=MRAM, each tasklet instead
+# reports the total number of cycles spent in MRAM processing: DMA read,
+# WRAM-to-WRAM copy, and DMA write.
