Book excerpt: DNA sequencing technology is quickly evolving. The latest developments ex- ploit nanopore sensing and microelectronics to realize real-time, hand-held devices. A critical limitation in these portable sequencing machines is the requirement of powerful data processing consoles, a need incompatible with portability and wide deployment. This thesis proposes a rst step towards addressing this problem, the construction of specialized computing modules { hardware accelerators { that can execute the required computations in real-time, within a small footprint, and at a fraction of the power needed by conventional computers. Such a hardware accel- erator, in FPGA form, is introduced and optimized specically for the basecalling function of the DNA sequencing pipeline. Key basecalling computations are identi- ed and ported to custom FPGA hardware. Remaining basecalling operations are maintained in a traditional CPU which maintains constant communications with its FPGA accelerator over the PCIe bus. Measured results demonstrated a 137X basecalling speed improvement over CPU-only methods while consuming 17X less power than a CPU-only method.
