You mean the ASP/CSP right? :-) Because scammy Creative called 8052 microcontroller on all of their cards a DSP = Digital Sound Processors (not Digital Signal Processors!).

Card with real DSP was called ASP = Advanced Signal Processor or CSP = Creative Signal Processor. ST18932, a bad one but still a DSP. Enough performance to implement 14.4kbps modem.
