Projects

Extending the RISC-V ISA

riscv

  • Custom synthesizable Verilog implementation of RV32-IM core and memory hierarchy
  • Added ISA + Microarchitectural extensions to accelerate:
    • Searching in Linear-Probed Hashsets (up to 10x speedup on high load-factors)
    • Breadth-First Search (average 2x speedup)

Processing-In-Memory: Sorting Algorithms

pim

  • Surveyed the ability of PIM to accelerate sorting techniques
    • Two base algorithms -- insertion/radix sort + merge -- showed similar results
    • PIM performed slower than C/C++ quicksort
    • Effect of PIM parameters (DPU-CPU tradeoffs, cache size) are analyzed

fpga

  • Fully-synthesizable Verilog design of the XC2064 from 1985
  • Created tooling for demonstration
    • Unit tests for LUT and CLB
    • Web GUI for interconnect bitstream generation
