Hillsboro, Oregon-based Lattice Semiconductor and Sunnyvale, California-based Synplicity said earlier this week that the two companies have linked in a deal over digital signal processing (DSP) technology. Synplicity and Lattice said that they have expanded a relationship to deliver ESL synthesis flow for DSP design. Financial arrangements of the deal were not disclosed. According to the firms, Synplicity's Synplify DSP software now supports Lattice's FPGA devices. The companies said the combination will allow companies in the aerospace, wireless, telecom, and digital multimedia areas to implement DSP algorithms. DSP is a software technique used to manipulate analog signals, such as wireless or audio signals; field programmable gate arrays (FPGAs) are programmable devices used to implement electronic circuits, and much more flexible than ASICs for developing hardware designs.
