MEM_CPY

MEM_CPY_XY rd,rs,rt,offset

Performs data transfer between memory units

• If X == 1, the source data address is GRF[rs] + offset; otherwise, the source data address is GRF[rs];
• If Y == 1, the destination data address is GRF[rd] + offset; otherwise, the destination data address is GRF[rd];
• The byte length of the data to be transferred is GRF[rt].

Example:

MEM_CPY_11 $3,$1,$2,1024
