An effective address (EA) is formed by adding a displacement to a base address. The displacement is
obtained by sign-extending the 16-bit D field to 32 bits. The base address is 0 when the RA field is 0,
and is the contents of register RA otherwise.
The contents of a series of consecutive registers, starting with register RS and continuing through
GPR(31), are stored into consecutive words starting at the EA.
