2.1 Underlying Processor Primitives
For a complete description of the SC100 architecture, refer to the SC140 DSP Core Reference Manual.
2.2 Fundamental Data Types
The SC100 architecture supports the fundamental data types shown in Figure 2-1.The mapping between
these data types and the C language fundamental data type is shown in Table 2-1. Fractional types are
supported in C using intrinsic functions; Table 2-2 shows the fractional types supported.
