16/32 BIT RISC/DSP

Hynix Semiconductor 

Overview

0-5

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

• 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

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

register

• Rotate left single word by content of register

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

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

• Compare unsigned/signed, Compare unsigned/signed immediate

• Compare bits, Compare bits immediate, Compare any byte zero

• Test number of leading zeros

• Set Conditional, save conditions in a register

• Branch unconditional and conditional (12 conditions)

• Delayed Branch unconditional and conditional (12 conditions)

• Call subprogram, unconditional and on overflow

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

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

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

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

• Software instruction, call an associated subprogram and pass a source operand and the

address of a destination operand to it

• DSP Multiply instructions:

signed and/or unsigned multiplication ⇒ single and double word product

• DSP Multiply-Accumulate instructions:

signed multiply-add and multiply-subtract ⇒ single and double word product sum and

difference

• DSP Halfword Multiply-Accumulate instructions:

signed multiply-add operating on four halfword operands ⇒ single and double word

product sum

• DSP Complex Halfword Multiply instruction:

signed complex halfword multiplication ⇒ real and imaginary single word product

• DSP Complex Halfword Multiply-Accumulate instruction:

signed complex halfword multiply-add ⇒ real and imaginary single word product sum
