They are implemented in a library-like module for easy access. The realisation follows the one described in chapter 4 of the DSP applications handbook1. Then, a software example will be described that may be downloaded from the accompanying zipped files. Finally, some data will be shown concerning the accuracy of the algorithms. 1 The Mathematical Library Routines 1.1 Using the Mathematical Routines The routines are developed as an easy-to-use library, which has to be linked to the user’s application. The library consists of two files. The file “mathfun.dsp” contains the assembly code for the subroutines. This package has to be compiled and can then be linked to an application. The user simply has to include the header file “mathfun.h”, which provides function-like calls to the routines. The following table summarises the set of macros that are defined in this library. Note that every function stores the result in the sr1 register, except for the division routine which makes the results available in ar.

For more information about the general structure of the application notes and including libraries into user applications refer to the Library Documentation File. Section 2 shows an example of usage of this library. In the following sections each routine is explained in detail with the relevant segments of code which is found in either “mathfun.h” or “mathfun.dsp”.

Note that the first four accept input in the unsigned 16.16 format and that the output is in various single precision format. The division routine expects a signed double precision value (for instance 1.31 or 8.24 …). Its output is in the ar register in a format that is determined by the input. It may also be noted that the DAG registers M5 and L5 must be set to 1 and 0 respectively and that they are not modified by the mathematical routines. The already mentioned call to Set_DAG_registers_for_math_function prepares these registers for the functions. It now becomes clear that this routine is necessary only once if M5 and/or L5 are not modified in another part of the user’s code, as shown in the example in section 2. Refer to the above-mentioned DSP applications handbook for more details on the routines described in the previous sections.

In the square root subroutine, the input is in 16.16 format, with unsigned integer in MR1 register and full fraction in MR0 register. Therefore, the valid input range for the square root subroutine is between 0 and 65536 (0xFFFF.FFFF). If the input value is out of the range between 0.5 and 1.0, the square root subroutine will scale the input in MR1 and MR0 registers by shift operation so that the scaled value will a Basic Mathematical Subroutines for the ADMC300 AN300-09 © Analog Devices Inc., January 2000 Page 5 of 16 fall into the valid equation range as input to equation ( 1) for computation. Obviously, the square root of the scaled input obtained from equation ( 1) must be multiplied by the square root of the scaling value to produce the square root of the original input as implemented in the following segment. .VAR/PM/RAM/SEG=USER_PM1 sqrt_coeff[5]; .INIT sqrt_coeff : 0x5D1D00, 0xA9ED00, 0x46D600, 0xDDAA00, 0x072D00; sqrt_: AX1=MR1; { store for knowing MSB } AR = PASS MR1; IF GE JUMP calculation; {MSB = 1 ?} SR = LSHIFT MR1 BY -1 (HI); { left shift by 1 } SR = SR OR LSHIFT MR0 BY -1 (LO); MR1 = SR1; MR0 = SR0; calculation: I5 = ^sqrt_coeff; {pointer to coeff. buffer} SE=EXP MR1 (HI); {Check for redundant bits} SE=EXP MR0 (LO); AX0=SE, SR=Norm MR1 (HI); SR=SR OR NORM MR0 (LO); MY0=SR1, AR=PASS SR1; IF EQ RTS; MR=0; MR1=base; {Load constant value} MF=AR*MY0 (RND), MX0=PM(I5,M5); {MF =x*x} MR=MR+MX0*MY0 (SS), MX0=PM(I5,M5); {MR = base + C1*x} CNTR=4; DO approx UNTIL CE; MR=MR+MX0*MF (SS), MX0=PM(I5,M5); approx: MF=AR*MF (RND); AY0=15; MY0=MR1, AR=AX0+AY0; {SE + 15 = 0?} IF NE JUMP scale; {No, compute scaling value} SR=ASHIFT MR1 BY -6 (HI); Jump modification; The next segment shows that the scaling value (1 2) 15 = ÷ + SE s is calculated where SE is the exponent detector value of the original input. If (SE+15) is negative, it means that original input is less than 0.5 and the approximated result of the scaled input is to be multiplied by the scaling number of 15 (1 2) ÷ + SE . Otherwise, the original value is larger than 1.0 and the approximated square root of the scaled input is multiplied with the reciprocal of the scaling number in order to get the result of the original input. It should be realised that equation ( 1) is for calculation of 0.5*Square_Root(x) and it is one of the factors under consideration when the subroutine Square_Root(x) shifts the result to get 8.8 format for the output of the original input. scale: MR=0; MR1=sqrt2a; {Load 1/sqrt2(2)} MY1=MR1, AR=ABS AR; AY0=AR; AR=AY0-1; IF EQ JUMP pwr_ok; CNTR=AR; {Compute S=(1/sqrt2(2))^(ABS(SE+15)) } DO compute UNTIL CE; compute: MR=MR1*MY1 (RND); pwr_ok: IF NEG JUMP frac; {If (SE+15) is negative, ...} AY1=0x0080; {Load a 1 in 9.23 format} AY0=0; {calculate 1/S, if (SE+15) positive } DIVS AY1, MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; DIVQ MR1; MX0=AY0; MR=0; MR0=0x2000; MR=MR+MX0*MY0 (US); { 9.23 format in result } a Basic Mathematical Subroutines for the ADMC300 AN300-09 © Analog Devices Inc., January 2000 Page 6 of 16 SR=ASHIFT MR1 BY 2 (HI); { to compensate the coefficient scaling } SR=SR OR LSHIFT MR0 BY 2 (LO); { and get 8.8 format } Jump modification; frac: MR=MR1*MY0 (RND); SR=ASHIFT MR1 BY -6 (HI); { compensate coefficient scaling } { and get 8.8 format} modification: AR = PASS AX1; IF GE RTS; { MSB = 1? } MY1 = sqrt_2; { if yes, the original left shifted 1 bit } MR = SR1 * MY1(uu); { multiplied by sqrt2(2) to get final result } SR1 = MR1; RTS; 1.4 Logarithm 1.4.1 Common Logarithm (Base 10) The following equation approximates the common logarithm of the input value 1
