PP data-unit registers
The data unit contains eight 32-bit general-purpose data registers (d0–d7) referred to as the D registers. The
d0 register also acts as the control register for EALU operations.

multiple flags (mf) register
The mf register records status information from each split ALU segment for multiple arithmetic operations. The
mf register may be expanded to generate a mask for the ALU. Figure 25 shows the mf register format.

PP address-unit registers
address registers
The address unit contains ten 32-bit address registers which contain the base address for address
computations or which can be used for general-purpose data. The registers a0 – a4 are used for local address
computations and registers a8–a12 are used for global-address computations.
