This paper presents a lightweight arithmetic for embedded signal processing, whose hardware complexity is similar to that of the integer one. In our simulations, its 16-bit version has 40.18dB signal to round-off error ratio over the IEEE single-precision floating-point arithmetic, which even out-performs the hand-optimized 32-bit code with integer arithmetic.
