Step Arithmetic instructions which are performed through the
ALU are divide and square root. Execution of each step of the
arithmetic operation takes one cycle, a 32/16-bit Step Divide
takes 21 cycles, and a 32/16-bit Step Square Root takes 25
cycles. Sign and scaling functions are controlled by the ALU
function and shift options, which are part of the coded
instruction contained in
. See Table 20 and Table 21
and the Programmer’s Reference Manual for details.

The HS-RTX2010RH Multiplier-Accumulator
The Hardware Multiplier-Accumulator (MAC) on the
HS-RTX2010RH functions as both a Multiplier, and a
Multiplier- Accumulator. When used as a Multiplier alone, it
multiplies two 16-bit numbers, yielding a 32-bit product in
one clock cycle. When used as a Multiplier-Accumulator, it
multiplies two 16-bit numbers, yielding an intermediate 32-bit
product, which is then added to the 48-bit Accumulator. This
entire process takes place in a single clock cycle.
The Multiplier-Accumulator functions are activated by I\O
Read and Write instructions to ASIC Bus addresses
assigned to the MAC.
The MAC’s input operands come from three possible
sources (see Figure 25):
