Electromagnetic radio frequency (RF) Spec-tral Convergence enables better utilization of available spectrum by reducing wastage and enabling multi-function tasks. However, to achieve these performance enhancements we need high-performance processors that can operate at low power while being flexible and easy to program. A promising solution to the above class of problems are coarse-scale heterogeneous processors. We have developed Domain-focused Advanced Software-reconfigurable Het-erogeneous (DASH) system-on-chip (SoC) to demonstrate the feasibility of such architectures. DASH SoC addresses domain requirements of spectral convergence by offering high throughput rates with minimal energy expenditure. It also offers a high degree of reprogrammability which enables adaptability to the domain of real-time joint communications and radar systems for applications such as spectral situational awareness, RF Convergence as well as positioning, navigation, and timing (PNT). In this paper, we perform hardware implementation of a joint-radar communications receiver on DASH SoC to validate our claims related to the capabilities of DASH SoC.
