### Description

The LHCb experiment at the LHC collider at CERN is undergoing a major upgrade in 2019-2021. The goal is to be able to operate at an instantaneous luminosity of $2\times 10^{33}$ cm$^{-2}$ s$^{-1}$, which is 5 times higher than the luminosity in previous LHCb runs. This requires a major redesign of the trigger system due to outstanding rate of beauty and charm hadron production. In the upgraded trigger, the hardware (level-0) stage will be dropped and the detector will be fully read out at 30 MHz. A fully software trigger will be operating at the collision frequency, where a full offline-quality reconstruction will be performed. In this talk, I will cover the design aspects of the software trigger, and will present the computing and physics performance of the high-level trigger for upgraded LHCb.
