• CNORM_PP1 Rd3 BS Rs0 Rs1 Rs2
• CNORM_PP2 Rd3 BS Rs0 Rs1 Rs2

Description:

CNORM_PP0 normal operation multiplies the contents of Rs0 and Rs1, adds the contents of Rs2 to the multiplication result, then moves the result to Rd3 according to BS (bank select). Low bank of register contains the Real part of complex number and High bank contains the Imaginary part. In short, it makes "(a*b+c)", where "a,b,c" are contents of registers Rs0, Rs1 and Rs2 correspondingly. Sign of final result is "+".

Other CNORM_PPX operations are similar. Except they perform complex conjugation on one or several complex numbers contained in registers. The "~" sign shows elements on which conjugation is performed.

Operations :

• CNORM_PP0 : a*b+c
• CNORM_PP1 : a*b+c~
• CNORM_PP2 : a*b~+c
• CNORM_PP3 : a*b~+c~
• CNORM_PP4 : a~*b+c
• CNORM_PP5 : a~*b+c~
• CNORM_PP6 : a~*b~+c
• CNORM_PP7 : a~*b~+c~

Instructions are stack conditioned.

Microcode patterns for other CNORM_PPX complex normal operations (see below) are differ only in MPC field, where the values are:

• for CNORM_PP0 : CN00
• for CNORM_PP1 : CN01
• for CNORM_PP2 : CN02
• for CNORM_PP3 : CN03
• for CNORM_PP4 : CN04
• for CNORM_PP5 : CN05
• for CNORM_PP6 : CN06
• for CNORM_PP7 : CN07

Microcode Pattern:

Takes 11 cycles to execute.
