D950-Core
Data buses (XD/YD and XA/YA) are provided externally. Data memories (RAM, ROM) and
peripherals registers are to be mapped in these address spaces.
Instruction bus (ID/IA) gives access to program memory (RAM, ROM). Each bus has its own
control interface
Table 3.1
Data/Instruction Bus and Corresponding Address Bus.
Depending on the calculation mode, the D950-Core DCU computes operands which can be
considered as 16 or 32-bit, signed or unsigned. It includes a 16 x 16-bit parallel multiplier able
to implement MAC-based functions in one cycle per MAC. A 40-bit arithmetic and logic unit,
including a 8-bit extension for arithmetic operations, implements a wide range of arithmetic
and logic functions. A 40-bit barrel shifter unit and a bit manipulation unit are included.
Tables 3.2 and 3.3 illustrate the different types of word length and word format available for
manipulation.
