API for User Written Fixed-Point SFunctions 1.0

API for User Written Fixed-Point and Floating-Point S-Functions.A supplement to Release 13 of Simulink and Fixed-Point Blockset.Version 0.9.0 Beta 1January 8, 2003Feedback on this beta should be sent toAndy BartlettThe MathWorks, Inc.3 Apple HillNatick, MA 01760Andy_Bartlett@mathworks.comThis zip file contains the files users need to write Simulink C S-Functionsthat directly handle fixed-point data types. The API is compatible withRelease 13 and beyond. These file should be expanded into a user selecteddirectory. This directory does NOT need to be under MATLABROOT.All the files are covered by:Copyright (c) 1984-2003 The MathWorks, Inc.All Rights Reserved.This supplement is compatible with Release 13 and later. MATLAB Version 6.5 (R13) Simulink Version 5.0 (R13) Fixed-Point Blockset Version 4.0 (R13)In Release 14, this API will be formally included in Simulink. It is expected,but not guaranteed, that if a Fixed-Point S-Functions is compiled in Release 13using this supplement, then the DLL, aka share object, will work withoutmodification in Release 14. If the S-Function is recompiled in Release 14,then care should be taken to recompile using the latest API files and not theAPI files included in this zip. When recompiling, it should NOT be necessaryto modify the S-Functions source code; the API will be backwards compatibile.The API for use in Simulink is described in the main header file. fixedpoint.hThe API for use in the TLC phase of Real-Time Workshop Code Generation isdescribed also. tlc_c/fix_published.tlcThe method of compiling user written fixed-point s-functions is described in. mex_sfun_user_fxp_examples.mThe C source files for several examples are given. sfun_user_fxp_*.cThe corresponding TLC files are also given. tlc_c/sfun_user_fxp_*.tlcModels that demostrate the example sfunctions are supplied. fxpdemo_sfun_user_*.mdl For Windows and Linux only, the executables are included inthis zip file. For other platforms, users must mexthe files themselves using mex_sfun_user_fxp_examples.m. sfun_user_fxp_*.dll sfun_user_fxp_*.mexglxA private file necessary for compiling the sfunctions is alsogiven. No direct use of the contents of this file should bemade. Direct use of the contents will create sfunctionsthat are not forward compatible with future Simulink Releases. fixedpoint.c
