One way of overcoming the main memory bottleneck is to move computation near memory, a paradigm known as processing-in-memory (PiM). Recent PiM techniques provide a promising way to improve the performance and energy efficiency of existing and future systems at no additional DRAM hardware cost. We develop the Processing-in-DRAM (PiDRAM) framework, the first flexible, end-to-end, and open source framework that enables system integration studies and evaluation of real PiM techniques using real DRAM chips. We demonstrate a prototype of PiDRAM on an FPGA-based platform (Xilinx ZC706) that implements an open-source RISC-V system (Rocket Chip). To demonstrate the flexibility and ease of use of PiDRAM, we implement two PiM techniques: (1) RowClone, an in-DRAM copy and initialization mechanism (using command sequences proposed by ComputeDRAM), and (2) D-RaNGe, an in-DRAM true random number generator based on DRAM activation-latency failures. Our end-to-end evaluation of RowClone shows up to 14.6X speedup for copy and 12.6X initialization operations over CPU copy (i.e., conventional memcpy) and initialization (i.e., conventional calloc) operations. Our implementation of D-RaNGe provides high throughput true random numbers, reaching 8.30 Mb/s throughput. Over the Verilog and C++ basis provided by PiDRAM, implementing the required hardware and software components, implementing RowClone end-to-end takes 198 (565) and implementing D-RaNGe end-to-end takes 190 (78) lines of Verilog (C++) code.
