PIM-DRAM

One of the key critical future elements about this world of compute is moving data about. Moving data requires power, to the point where calling data from memory can consume more power than actually doing ‘compute’ work on it. This is why we have caches, but even these require extensive management built in to the CPU. For simple operations, like bit-shifts or AND operations, the goal is to move the ability to do that compute onto the main DRAM itself, so it doesn’t have to shuttle back and forth. This year at Hot Chips, UPMEM is one of the first companies to showcase their new technology.
