Abstract
A memory controller includes an arbiter, a vector arithmetic logic unit (VALU), a read buffer and a write buffer both coupled to the VALU, and an atomic memory operation scheduler. The VALU performs scattered atomic memory operations on arrays of data elements responsive to selected memory access commands. The atomic memory operation scheduler is for scheduling atomic memory operations at the VALU; identifying a plurality of scattered atomic memory operations with commutative and associative properties, the plurality of scattered atomic memory operations on at least one element of an array of data elements associated with an address; and commanding the VALU to perform the plurality of scattered atomic memory operations.
