In this paper, we present an efficient hardwareimplementation of a video encoder optimized for ultra low-latency, using the Logarithmic Hop Encoding algorithm. This design provides the following features: (i) A maximum marginal output latency of 23 clock cycles, (ii) small area requirements, (iii) proven rate up to 95 Millions of pixels per second in a low-end FPGA (i.e. FHD video can be streamed), (iv) on-the-fly configuration, (v) scalable architecture. The proposed design has been tested in a real video transmission scenario, where the video transmitter prototype is implemented using a ZynqBerry board, leveraging all SoC capabilities.
