Address Pointer Operation

“[IDXi⊗]” stands for

[IDXi](IDXi) ← (IDXi)

(no-op)

[IDXi+](IDXi) ← (IDXi) + 2

(i=0,1)

[IDXi-]

(IDXi) ← (IDXi) - 2

(i=0,1)

[IDXi + QXj](IDXi) ← (IDXi) + (QXj)

(i, j =0,1)

[IDXi - QXj](IDXi) ← (IDXi) - (QXj)

(i, j =0,1)

“[Rwn⊗]” stands for

[Rwn]

(Rwn)

← (Rwn)

(no-op)

[Rwn

(Rwn)

← (Rwn) + 2

(n=0-15)

[Rwn-]

(Rwn)

← (Rwn) - 2

(n=0-15)

[Rwn

+ QRj]

(Rwn)

← (Rwn) + (QRj)

(n=0-15; j =0,1)

[Rwn - QRj]

(Rwn)

← (Rwn) - (QRj)

(n=0-15; j =0,1)
