The 17 x 17-bit multiplier is capable of signed or unsigned operation and can multiplex its output using a scaler to support either 1.31 fractional (Q31) or 32-bit integer results. Unsigned operands are zero-extended into the 17th bit of the multiplier input value when Crack Microcontroller.

Signed operands are sign-extended into the 17th bit of the multiplier input value. The output of the 17 x 17-bit multiplier/scaler is a 33-bit value which is sign-extended to 40 bits. Integer data is inherently represented as a signed two’s complement value, where the MSB is defined as a sign bit if Crack Microcontroller.

Generally speaking, the range of an N-bit two’s complement integer is -2N-1 to 2N-1 – 1. For a 16-bit integer, the data range is -32768 (0x8000) to 32767 (0x7FFF) including ‘0’. For a 32-bit integer, the data range is -2,147,483,648 (0x8000 0000) to 2,147,483,645 (0x7FFF FFFF) before Crack Microcontroller.

When the multiplier is configured for fractional multiplication, the data is represented as a two’s complement fraction, where the MSB is defined as a sign bit and the radix point is implied to lie just after the sign bit (QX format). The range of an N-bit two’s complement fraction with this implied radix point is -1.0 to (1 – 21-N) after Crack Microcontroller.

For a 16-bit fraction, the Q15 data range is -1.0 (0x8000) to 0.999969482 (0x7FFF) including ‘0’ and has a precision of 3.01518×10-5. In Fractional mode, the 16×16 multiply operation generates a 1.31 product which has a precision of 4.65661 x 10-10. The same multiplier is used to support the MCU multiply instructions which include integer 16-bit signed, unsigned and mixed sign multiplies if Crack Microcontroller.

The MUL instruction may be directed to use byte or word sized operands. Byte operands will direct a 16-bit result, and word operands will direct a 32-bit result to the specified register(s) in the W array. In addition to adder/subtracter saturation, writes to data space may also be saturated but without affecting the contents of the source accumulator when Crack Microcontroller.

The data space write saturation logic block accepts a 16-bit, 1.15 fractional value from the round logic block as its input, together with overflow status from the original source (accumulator) and the 16-bit round adder. These are combined and used to select the appropriate 1.15 fractional value as output to write to data space memory after Crack Microcontroller.

If the SATDW bit in the CORCON register is set, data (after rounding or truncation) is tested for overflow and adjusted accordingly, For input data greater than 0x007FFF, data written to memory is forced to the maximum positive 1.15 value, 0x7FFF. For input data less than 0xFF8000, data written to memory is forced to the maximum negative 1.15 value, 0x8000 before Crack Microcontroller.

The MSb of the source (bit 39) is used to determine the sign of the operand being tested. If the SATDW bit in the CORCON register is not set, the input data is always passed through unmodified under all conditions. The barrel shifter is capable of performing up to 16-bit arithmetic or logic right shifts, or up to 16-bit left shifts in a single cycle. The source can be either of the two DSP accumulators, or the X bus (to support multi-bit shifts of register or memory data) if Crack Microcontroller.

The shifter requires a signed binary value to determine both the magnitude (number of bits) and direction of the shift operation. A positive value will shift the operand right. A negative value will shift the operand left. A value of ‘0’ will not modify the operand. The barrel shifter is 40 bits wide, thereby obtaining a 40-bit result for DSP shift operations and a 16-bit result for MCU shift operations.

Data from the X bus is presented to the barrel shifter between bit positions 16 to 31 for right shifts, and bit positions 0 to 16 for left shifts.
