Syntax and Functions

CCS C Compilers include Standard C Constructs, numerous Pre-Processor Functions, and hundreds of Built-In Functions. All practical ANSI C standard requirements are implemented. C syntax and special functions have a uniform syntax across all chip families, allowing for migration to a new chip trivial.

Data Types

  • int1
  • int8
  • int16
  • int32
  • int48*
  • int64*
  • float
  • float48*
  • float64*
  • short
  • char
  • int
  • long
  • double*
  • _fixed(n)
  • unsigned
  • signed
  • void
Items marked with * are for 24-bit parts only.

Standard C Syntax

  • if, else, while, do, switch, case, for, return, goto, break, continue
  • ! ~ ++ -- * = = , & |
  • * / % << >> ^ && || ?:
  • <= < > >= == !=
  • = += -= *= /= %= >>= <<= &= ^=m |=
  • typedef, static, auto, const, enum, struct, union
  • Arrays up to 5 subscripts
  • Structures and Unions may be nested
  • Custom bit fields (1-8 bits) within structures
  • Enumurated types
  • Constant variables, arrays, structures and strings
  • Full function parameter support (any number and kind)
  • C++ reference parameters and comments allowed
