ABSTRACT:
A compiler for a digital signal processor allows the designer to specify separately function, accuracy and throughput. The compiler employs a word structure having the signal attributes of bits, digits and subwords which all have a direct relationship to the size of the processor and throughput. From a budget of working bits and clock cycles implicit in the specification of accuracy and throughput the compiler is able to choose the optimal word structure for the application. The compiler can also propagate throughout an icon network, used for the specification of function, various estimation attributes such as word growth and quantisation noise, which allow the designer to observe the effect of design changes without recourse to simulation. A specific example of design employing a specified architecture and a specified computational grain is explained.
