Abstract

A technique used to accelerate an adaptive optics simulation platform using reconfigurable logic is described. The performance of parts of this simulation has been improved by up to 600 times (reducing computation times by this factor) by implementing algorithms within hardware and enables adaptive optics simulations to be carried out in a reasonable time scale. This demonstrates that it is possible to use reconfigurable logic to accelerate computational codes by very large factors when compared with conventional software approaches, and this has relevance for many computationally intensive applications. The use of reconfigurable logic for high performance computing is currently in its infancy and has never before been applied to this field.

Figures (6)

Fig. 1
Fig. 1

Wavefront sensingprocess for a typical Shack–Hartmann wavefront sensor.

Fig. 2
Fig. 2

Parallelization of the wavefront sensor pipeline within the FPGA. All stages operate simultaneously. Here, NOP means no operation is computed, i.e., the input data is not valid.

Fig. 3
Fig. 3

Performance increase when using a FPGA instead of a CPU for wavefront sensing pipeline algorithms, as a function of the FPGA clock rate. The dotted line above 170 MHz shows the speeds at which the FPGA algorithm becomes unreliable due to overclocking. Here, the centroid locations of 1024 Shack–Hartmann subapertures have been computed at each FPGA clock frequency.

Fig. 4
Fig. 4

Computation time for the wavefront sensing pipeline in hardware (solid curve) and software (dotted curve) as a function of the number of subapertures to be evaluated.

Fig. 5
Fig. 5

Ratio of CPU to FPGA computation time for the wavefront sensing pipeline as a function of the number of subapertures to be evaluated. A typical current AO system will contain 100 subapertures, while future AO systems are designed with over 100,000 subapertures. The number of image integrations carried out before the CCD readout is simulated is 1 (solid curve), 2 (dotted curve), 4 (dashed curve) and 8 (dotted–dashed curve).

Fig. 6
Fig. 6

Ratio of CPU to FPGA computation time for the wavefront sensing pipeline as a function of the number of pupil phase values per subaperture (first number for each bar) and the number of simulated CCD pixels (in each dimension) per subaperture (second number for each bar).
