The personal communication systems of the future will augment the mobile phone concept to include multimedia services such as: digitized speech, data, e-mail, paging, facsimile, GPS, still images transmission, and real time video. To that end, we have employed delay insensitive asynchronous design techniques to implement a mathematical morphology processor for image coding using GaAs technology. For the implementation we introduce a modified version of the DCVSL family, in order to achieve ultra-fast data rates. Simulation of architecture implementation in GaAs MESFET 0.6~ \mu m technology demonstrate the reliability of this ASIC system for the high end image processing applications with a bit-rate of 4~Gbits/s. This is the first ever reported design of an asynchronous wave front morphological processor using GaAs technology for speed enhancement.
