Overview: MS2014 CD ________ fe!;i~!.~!! A_D_V_A_N_CE_I_N_FO_R_M_A_T_IO_N Advance information is issued to advise Customers of new additions to the Plessey Semiconductors range which, nevertheless, still have 'pre-production' status. Details given may, therefore, change without notice although we would expect this performance data to be representative of 'full production' status product in most cases. Please contact your local Plessey Semiconductors Sales Office for details of current status. MS2014 DIGITAL FILTER AND DETECTOR (FAD) The MS2014 is a real time general purpose digital signal processor (DSP) which is easily programmed to perform digital filtering and level detection. The architecture of the FAD comprises a cascadable second order recursive filter and level detector using dedicated multipliers, adders and delay elements.
The data controlling the response of the MS2014 is stored in an external PROM or RAM and consists of a list of filter coefficients and comparison levels. This Simple data format means that the user does not need an expensive development system at the design stage (in contrast to other DSP devices, which use microprocessor-based structures and require considerable software development effort to realise their function). The off-chip data memory allows for easy adaptive control, even when complicated algorithms are to be implemented.
The filter and detector have been designed to give maximum flexibility in use and can easily generate most of the functions required in tone detector, spectral analysis, adaptive filter and speech synthesis systems.
