Introducing the Semi-Soft algorithm
The Semi-Soft algorithm idea isn’t new, and it has been around for many decades now since FPGA technology became prevalent in the electronics industry. It is a combination of hardware and software from the initial architecture development stages and is used to implement compute algorithms.
Using the Semi-Soft algorithm approach in the Zynq-based SoCs
When targeting a Zynq SoC, the hardware and software split between the PEs is considered from the start of the project rather than all the computing algorithms in the software being implemented, profiled, having the bottlenecks pinpointed (if any), and then hardware-accelerated. There is nothing wrong with the latter approach – it is just limiting in what can be achieved when targeting an ASIC technology to implement the design. Once the overall SoC architecture and microarchitecture have been defined, it is hard to modify the design at a later stage and introduce the optimal communication...
