0.1. GMS30C2116/32 RISC/DSP (continued)

¡ Ü Memory address modes: register address, register post-increment, register + dis-

placement (including PC relative), register post-increment by displacement (next

address), absolute, stack address, I/O absolute and I/O displacement

¡ Ü Load, all data types, bytes and half words right adjusted and zero- or sign-expanded,

execution proceeds after Load until data is needed

¡ Ü Store, all data types, trap when range of signed byte or half word is exceeded

¡ Ü Move, Move immediate, Move double-word

¡ Ü Logical instructions AND, AND not, OR, XOR, NOT, AND not immediate, OR

immediate, XOR immediate

¡ Ü Mask source and immediate ⇒ destination

¡ Ü Add unsigned/signed, Add signed with trap on overflow, Add with carry

¡ Ü Add unsigned/signed immediate, Add signed immediate with trap on overflow

¡ Ü Sum source + immediate ⇒ destination, unsigned/signed and signed with trap on

overflow

¡ Ü Subtract unsigned/signed, Subtract signed with trap on overflow, Subtract with carry

¡ Ü Negate unsigned/signed, Negate signed with trap on overflow

¡ Ü Multiply word ∗ word ⇒ low-order word unsigned or signed, Multiply

word ∗ word ⇒ double-word unsigned and signed

¡ Ü Divide double-word by word ⇒ quotient and remainder, unsigned and signed

¡ Ü Shift left unsigned/signed, single and double-word, by constant and by content of

register, Shift left signed by constant with trap on loss of high-order bits

¡ Ü Shift right unsigned and signed, single and double-word, by constant and by content of

register

¡ Ü Rotate left single word by content of register

¡ Ü Index Move, move an index value scaled by 1, 2, 4 or 8, optionally with bounds check

¡ Ü Check a value for an upper bound specified in a register or check for zero

¡ Ü Compare unsigned/signed, Compare unsigned/signed immediate

¡ Ü Compare bits, Compare bits immediate, Compare any byte zero

¡ Ü Test number of leading zeros

¡ Ü Set Conditional, save conditions in a register

¡ Ü Branch unconditional and conditional (12 conditions)

¡ Ü Delayed Branch unconditional and conditional (12 conditions)

¡ Ü Call subprogram, unconditional and on overflow

¡ Ü Trap to supervisor subprogram, unconditional and conditional (11 conditions)

¡ Ü Frame, structure a new stack frame, include parameters in frame addressing, set frame

length, restore reserve frame length and check for upper stack bound

¡ Ü Return from subprogram, restore program counter, status register and return-frame
