How many bits is DSP?

Most fixed-point DSP chips have 16, 24 or 32 bit integer operations.

What is fixed-point precision?

The precision of a fixed-point number is the difference between successive values representable by its data type and scaling, which is equal to the value of its least significant bit. The value of the least significant bit, and therefore the precision of the number, is determined by the number of fractional bits.

What is fixed-point in DSP?

Fixed-point DSPs are designed to represent and manipulate integers – positive and negative whole numbers – via a minimum of 16 bits, yielding up to 65,536 possible bit patterns (2¹⁶).

What is 16 bit fixed-point?

Fixed point representation is used to store integers, the positive and negative whole numbers: … -3, -2, -1, 0, 1, 2, 3, …. High level programs, such as C and BASIC, usually allocate 16 bits to store each integer. In the simplest case, the 2¹⁶ = 65,536 possible bit patterns are assigned to the numbers 0 through 65,535.
