These inputs can be treated as either signed (two’s
complement) or unsigned integers, depending on the form of
the instruction used. In addition, if the ROUND option is
selected, the Multiplier can round the result to 16 bits. Note
that the MAC instructions do not pop the Parameter Stack;
the contents of
and

remain intact.
For the Multiplier, the product is read from the Multiplier High
Product Register,
, which contains the upper 16 bits of
the product, and the Multiplier Low Product Register,
which contains the lower 16 bits. For the Multiplier-
Accumulator, the accumulated product is read from the
Multiplier Extension Register,
upper 16 bits, the
, which contains the middle 16 bits,
and the
, which contains the low 16 bits. The registers
may be read in any order, and there is no requirement that
all registers be read. Reading from any of the three registers
moves its value into

If 32-bit precision is not required, the multiplier output may be
rounded to 16 bits. This is accomplished by setting the ROUND
bit in the Interrupt Base/Control Register,
ROUND bit is set to 1, all operations that use the Multiplier
automatically round the least significant 16 bits of the result into
the most significant 16 bits. The rounding is achieved by adding
8000H to the least significant 16 bits (during the same cycle as
the multiply). Thus, if the ROUND bit is set:

The multiply instructions suppress interrupts during the
multiplication cycle. Reading
suppresses interrupts during the read. This allows a
multiplication operation to be performed, and both the upper
and lower registers to be read sequentially, with no danger of
a non-NMI interrupt service routine corrupting the contents
of the registers between reads. The multiply-accumulate
instructions do not suppress interrupts during instruction
execution.

The HS-RTX2010RH On-Chip Barrel Shifter And
Leading Zero Detector
The HS-RTX2010RH has both a 32-bit Barrel Shifter and a
32-bit Leading Zero Detector for added floating-point and
DSP performance. The inputs to the Barrel Shifter and
Leading Zero Detector are the top two elements of the
Parameter Stack, the
and
TOP
registers.
The Barrel Shifter uses a 5-bit count stored in the
Register to determine the number of places to right or left
shift the double word operand contained in the
registers. The output of the Barrel Shifter is stored in
the
and
registers, with the top 16 bits in
and the bottom 16 bits in
