PRELIMINARY INFORMATION AUG 02, 2011
The hardware multiplier is a peripheral and is not part of the EL16 CPU. This means, its activities do not inter-
fere with the CPU activities. The multiplier registers are peripheral registers that are loaded and read with
CPU instructions.
The hardware multiplier supports:
The hardware multiplier supports unsigned multiply, signed multiply, unsigned multiply accumulate, and
signed multiply accumulate operations. The type of operation is selected by the address the first operand is
written to. The hardware multiplier has two 16-bit operand registers, OP1 and OP2, and three result registers,
SumLo, SumHi, and SumExt. SumLo stores the low word of the result, SumHi stores the high word of the
result, and SumExt stores information about the result.
