Abstract: In various signal processing algorithms such as machine learning and multimedia digital signal processing, energy consumption can be minimized by the use of approximate computing, since these applications are generally known to have error tolerable characteristics. A novel approximate computing scheme suitable for realizing a double throughput energy-efficient multiply-accumulate (MAC) processing is presented in this paper. In this work, different approximate multipliers are used in an interleaved way to compensate errors in the opposite direction during accumulate operations, which minimizes the error accumulation limiting the approximate range present in the previous works. For the balanced error accumulation, the approximate 4-2 compressors generating errors in the opposite direction are designed and based on the probabilistic analysis, positive and negative multipliers are then carefully developed to provide a similar error distance. The new architecture is extended to create a versatile double throughput MAC (DTMAC) unit that efficiently performs either Multiply-Accumulate or simple Multiplication operation. The new architecture is further extended to create a versatile double-throughput MAC (DTMAC) unit that efficiently performs either multiply-accumulate or multiply operations for N-bit, 1xN/2 - bit, or 2xN/2-bit operands. In comparison to a fixed-function 16-bit MAC unit, 8-bit multiply- accumulate operations can be executed with higher energy efficiency on a 16-bit DTMAC unit.
