Overview

A numerically controlled oscillator (NCO) is a digital signal generator, which synthesizes a discrete-time, discrete-valued representation of a sinusoidal waveform. You can typically use NCOs in communication systems. In such systems, they are used as quadrature carrier generators in I-Q mixers, in which baseband data is modulated onto the orthogonal carriers in one of a variety of ways.

Key features

  • 32-bit precision for angle and magnitude
  • Source interface compatible with the Avalon® interface specification
  • Multiple NCO architectures:
    • Multiplier-based implementation using digital signal processing (DSP) blocks or logic elements (LEs), single cycle and multi-cycle
    • Parallel or serial CORDIC-based implementation
    • ROM-based implementation using embedded array blocks (EABs), embedded system blocks (ESBs), or external ROM
  • Single or dual outputs (sine/cosine)
  • Variable width frequency modulation input
  • Variable width phase modulation input
  • User-defined frequency resolution, angular precision, and magnitude precision
  • Frequency hopping
  • Multichannel capability
  • Simulation files and architecture-specific testbenches for VHDL and Verilog HDL
  • Dual-output oscillator and quaternary frequency shift keying (QFSK) modulator example designs

Minimum RISC-V: Maximum FPGA Efficiency

In this work the authors first design a lightweight but deeply pipelined RISC-V core that can run above 700 MHz in a mid-range device and that is capable of retiring one instruction per clock under ideal conditions. They then develop and demonstrate a new optimization method that compiles the final application binary and a specialized processor instance contemporaneously.
