The MacSpace Value Proposition may be represented along five axes of abstract values, as depicted below in Figure 1, which shows the state-of-the-art value proposition as the yellow pentagon whereas the MacSpace value proposition covers the significantly larger green pentagon. The five axes are:
- Floating Point Performance requirements: MacSpace Processor targets 20 GFLOPS, whereas SOTA ITAR-free space DSPs are planned to achieve 1.6 GFLOPS.
- Fixed Point Performance: SOTA emerging space DSP chips are designed to achieve no more than 6 GOPS, while the highly-parallel MacSpace Processor targets 75 GMACs and 150 GOPs.
- Performance/Power: MacSpace Processors are expected to achieve twice the performance-to-power ratio in comparison with the emerging SOTA DSP chips.
- Ease of Programming: SOTA DSP chips are based on a careful balance of computation and data access operations. For the programmer, maintaining such a balance is much more difficult to optimise vs. using standard parallel programming models and standard languages as supported by MacSpace.
- Space Availability: MacSpace is based on 65nm technology – a game changer in terms of space technology and the manufacturing process and being developed in parallel to the MacSpace project. Other SOTA devices in Europe do not use this technology. This will result in the ability to increase MIPS, MIPs/Watt, on chip memory and ad high speed interfaces in MacSpace.
