Abstract

A digital system 1 comprises receiving means (5) for receiving one or more performance indicators or parameters from software (6) controlling the execution of an application (3). Based on the performance indicators received by the receiving means (5), a tuning circuit (7) is provided for tuning the frequency (f), supply voltage (Vdd) and/or the transistor threshold voltage (Vb) of the digital system (1). In addition, pipeline configuration means (8) are provided for configuring the pipeline of the digital system (1) based on a pipeline depth determined by selecting means (10). The selecting means (10) is configured to select the pipeline depth (Pd) based on the frequency (f), supply voltage (Vdd), transistor threshold voltage (Vb), and according to whether the application requires maximum throughput or minimum latency.
