MilSpec

A Suite of National Defense-Inspired Benchmarks

MilSpec is a set of open-source benchmarks targeted at national defense applications – but also useful for the broader accelerator design space. These benchmarks focus on end-to-end applications that exercise a wide range of signal processing, communications, image processing/computer vision, knowledge formation, and other capabilities.

Benchmark Functions Getting Started Code/Data External Source/Docs Updated

MUSIC

The MUltiple SIgnal Classification (MUSIC) algorithm is a method for estimating the direction of arrival of signals received by an antenna array. This standalone test inputs a simulated set of signal samples, applies the MUSIC algorithm, and measures the angle estimation error and compute time.

Linear algebra Getting started with MUSIC MUSIC Code/Data 06/01/2020

Passive Radar

Passive radar is a radar mechanism where the receiver relies on an external signal source, rather than transmitting radar pulses itself. This end-to-end test processes a time-series set of signal samples to determine target position and measures the compute time for each processing step.

Transcendental Math

Transcendental functions are a class of non-polynomial operations (sin, log, exp, etc.) that are fundamental to various algorithms, particularly in signal processing. This benchmark tests the performance of several methods for approximating transcendental function values at varying degrees of precision.

Synthetic Aperture Radar (SAR)

Synthetic Aperture Radar constructs images based on data from a moving radar platform (e.g., mounted on an aircraft to scan a large ground region). This benchmark tests an end-to-end sensor processing pipeline, forming complete images from synthetically generated radar returns and then identifying objects in those returns.

Real-Time Object Detection + Tracking (RTTrack)

This benchmark uses a visual processing system to identify and track multiple human actors simultaneously in a variety of recorded video clips.

Computer vision, multiple object tracking Getting Started with RTTrack RTTrack Code/Data 01/21/2020

Linear Assignment

Assignment problems use combinatorial optimization to find the most efficient mapping between two sets - for instance, when mapping a large number of tasks to agents that will perform them, as might be required with autonomous cooperative swarms of robots. This benchmark runs a synthetic test of the auction, Hungarian, and Jonker-Volgenant algorithms for finding such mappings.

Combinatorial optimization, linear algebra, matrix math Getting Started with LAP Linear Assignment Code/Data 03/16/2020

Pulse-Doppler Radar

Pulse-Doppler radar transmits a series of radar pulses and then detects object motion per the Doppler effect. It is commonly used for tracking airborne targets or in weather applications. This benchmark processes simulated radar returns with a four-step pipeline to find Doppler peaks and detect object positions/velocities.

Epipolar Geometry

Epipolar geometry defines the relationships between points across multiple perspectives on a three-dimensional scene. This benchmark computes corresponding points in pairs of images using multiple user-selectable algorithms.

Optical Flow

Optical flow is a means of detecting the relative motion of a scene and an observer. This benchmark identifies points of interest (whose motion can be easily tracked) in an image, then identifies the corresponding points in a second image and estimates relative motion.

Matched Filtering

Matched filtering can improve an effective signal-to-noise ratio by "matching" a known signal template to an unknown input signal expected to follow that template. This test inputs a signal with configurable random noise, applies a matched filter, and then measures the output error rate and compute time.

Wavelet Processing

Wavelets are signal pulses, with finite duration, based on assorted mathematical functions. They are useful for assorted signal and image processing applications e.g. noise reduction; this test evaluates the performance of a discrete wavelet transform algorithm on denoising a set of input images (or synthetic vectors).
