The role of the Embedded Software Engineer is to design, develop and test embedded software for CSR’s wireless chips, focussing on CSR’s Kalimba DSP.
Working as part of a small team, the work involves developing new audio processing algorithms, working on DSP frameworks and applications, integrating algorithms into the DSP framework and developing test scenarios and debugging problems.
Most of the software development will be in Kalimba DSP assembly, but various other parts of the system use C. Various different programs are used on PCs for debugging/testing and emulating host processor functionality. These are written in a variety of languages including C, C++, python, perl, Matlab and tcl.
