AB  - This paper addresses the problem of performing time series analysis on-board a 
      spacecraft, where the number of constraints is much bigger than for applications 
      running in regular (i.e., ground-based) environments. An objective of modern 
      spacecraft technologies designed for space exploration is to perform on-board 
      data processing tasks, in order to increase the amount of data available for 
      scientific analysis. Field Programmable Gate Array (FPGA) devices are considered 
      as good candidates for hardware implementations of such systems. In order to 
      optimize the usage of on-board resources, FPGAs share their resources between 
      several digital signal processing (DSP) algorithms. In this paper, we describe 
      the design and implementation of such an optimized design where two DSP 
      algorithms are implemented on the same FPGA: (1) the power spectral density and 
      (2) the multiscale probability distribution functions. The entire implementation 
      process is described in detail, including a discussion about the main 
      architectural choices. The proposed solutions focus on optimization of area, 
      speed, and power. The tests performed, on both synthetic and real data, 
      demonstrate the feasibility of our approach and constitute the first step toward 
      porting the design on space-grade FPGAs.
