FPGA Parallelism

Technique

A hardware-acceleration technique that, in the provided sources, is used to increase throughput by exploiting concurrency on FPGA devices. The evidence shows two concrete forms: running multiple CPU verification targets in parallel in ISAAC, and using fully pipelined image-processing units in a retinal vessel detector.

FPGA Parallelism

FPGA parallelism is a technique for increasing throughput by mapping work onto concurrent FPGA hardware structures. In the provided sources, it appears in two concrete forms:

Parallel verification back-ends: ISAAC uses a lightweight forward-snapshot mechanism and a decoupled co-simulation architecture so that a single Instruction Set Simulator (ISS) can drive multiple Designs Under Test (DUTs) in parallel, explicitly exploiting FPGA parallelism to improve simulation throughput.
Fully pipelined accelerators: a retinal blood-vessel segmentation design on Zynq increases throughput by using fully pipelined functional units, reusing computations, and optimizing bit-width while benefiting from FPGA parallelism.
