CADAC: A Controlled-Precision Decimal Arithmetic Unit
April 1983 (vol. 32 no. 4)
pp. 370-377
This paper describes the design of an arithmetic unit called CADAC (clean arithmetic with decimal base and controlled precision). Programming language specifications for carrying out "ideal" floating-point arithmetic are described first. These specifications include detailed requirements for dynamic precision control and exception handling, along with both complex and interval arithmetic at the level of a programming language such as Fortran or PL/I.
Index Terms:
variable precision, Arithmetic unit, language requirements, numerical computation, pipelined multiplier
