“…However, recent radio access network virtualization technologies, such as Open RAN and vRAN, have encouraged telecom operators to implement signal processing using ASIPs with greater flexibility and programmability. The work [10] implements generalized frequency division multiplexing based on RISC-V vector extension, demonstrating the potential of RISC-V in signal processing. A typical signal processing ASIP based on RISC-V custom extensions is Edge Q [11].…”

“…The RISC-V offers designers an alternative that permits customization and innovation in communication ASIPs. Recent works have designed signal processing [10], [11], error correction coding [43], and radio resource management [44], [54] RISC-V ISA extensions to build flexible and efficient communication ASIPs. Signal processing technologies (such as frequency division multiplexing, beamforming, etc.)…”

“…The recent introductions of ISA vector extensions for low-power CPUs, such as ARM's M-Profile Vector Extension or the RISC-V Vector extension, however open up new possibilities in this regard [26], [27]. For instance, an implementation of a generalized frequency division multiplexing (GFDM) demodulator with the RISC-V Vector extension demonstrated a speedup of up to 60 times compared to the scalar base case [28].…”

“…Its flexibility implies a better fine-tuning of the data sizes involved in the computation than standard narrow-SIMD units, which rarely support arithmetic and memory instructions for data formats below 8-bits, and typically neither cover all the possible data size granularities nor support mixed-precision computations. As an example, the current RISC-V vector extension [131] has deprecated its support for narrow-SIMD computations (i.e., Zvediv), account for different data sizes between the data sources. Thus, Bison-e is capable of computing compressed data and performing flexible SIMD-style computations, whose width is proportional to the data size of every operation operand, without associated overheads.…”
