Engineering

From FPGA logic to host-side data access.

AuroraCore supports hardware architecture design, low-latency PCIe data paths, DMA transfer solutions, host-side communication interfaces, and driver adaptation.

PCIe Architecture

Endpoint design, BAR mapping, register models, queue behavior, interrupt strategy, and transfer flow definition.

FPGA Data Paths

Buffering, packet framing, clock-domain crossing, stream arbitration, and latency-sensitive datapath implementation.

DMA Transfer

Host memory movement, descriptor handling, throughput tuning, backpressure behavior, and acquisition stream validation.

Driver Adaptation

Host-side communication interfaces, application integration points, test utilities, and deployment-specific driver adaptation.

Delivery Workflow

Engineering engagement from requirements to validation.

Requirement Review

Capture host platform, PCIe generation, interface timing, throughput, latency, operating system, and environmental constraints.

Architecture Definition

Define endpoint mapping, FPGA data paths, buffer strategy, DMA scheduling, register model, and driver adaptation scope.

Prototype Integration

Bring up FPGA logic, host communication, test utilities, and representative acquisition or control workloads on the target platform.

Validation Package

Deliver measured results, configuration notes, interface documentation, and deployment recommendations for the agreed revision.

Anonymous Case Note

Acquisition Stream Validation

A reference PCIe Gen3 x4 acquisition path was validated on a workstation-class host with continuous DMA streaming, fixed-size host buffers, and application-level integrity checks.

Sustained Transfer: 3.2 GB/s reference stream
Run Duration: 8 hour continuous validation
Observed Data Errors: 0 in reference workload

Anonymous Test Data

Control-Path Latency Profile

A low-overhead endpoint profile was measured using host-issued command transactions, FPGA acknowledgement logic, and timestamped user-space test utilities.

Median Round Trip: 18 us in reference setup
99th Percentile: 44 us under moderate host load
Workload: Command, telemetry, interrupt handling
