WebThe TMS9900 has three internal 16-bit registers — Program counter (PC), Status register (ST), and Workspace Pointer register (WP). The WP register points to a base address in external RAM where the processor's 16 general purpose user registers (each 16 bits wide) are kept. This architecture allows for quick context switching; e.g. when a subroutine is … WebRight Shift ( >> ): Right shift operator is a binary operator which shift the some number of bits, in the given bit pattern, to the right and append 1 at the end. Right shift is equivalent to dividing the bit pattern with 2k ( if we are shifting k bits ). 4 …
