PICAXE

uM-FPU Floating Point Coprocessor

Product Details

The uM-FPU V2 Floating Point Coprocessor provides a huge amount of mathematical co-processing power to the PICAXE chip. It interfaces via fast I2C bus, and so can be used with an M2, X1 or X2 series PICAXE chip.

Features:

  • 8-pin integrated circuit.
  • I2C compatible interface up to 400 kHz
  • 32 byte instruction buffer
  • Sixteen 32-bit general purpose registers for storing floating point or long integer values
  • Five 32-bit temporary registers with support for nested calculations (i.e. parenthesis)
  • 32-bit Floating Point Operations
    • Set, Add, Subtract, Multiply, Divide
    • Sqrt, Log, Log10, Exp, Exp10, Power, Root
    • Sin, Cos, Tan
    • Asin, Acos, Atan, Atan2
    • Floor, Ceil, Round, Min, Max, Fraction
    • Negate, Abs, Inverse
    • Convert Radians to Degrees, Convert Degrees to Radians
    • Read, Compare, Status
  • 32-bit Long Integer Operations
    • Set, Add, Subtract, Multiply, Divide, Unsigned Divide
    • Incrment, Decrement, Negate, Abs
    • And, Or, Xor, Not, Shift
    • Read 8-bit, 16-bit, and 32-bit
    • Compare, Unsigned Compare, Status
  • Conversion Functions
    • Convert 8-bit and 16-bit integers to floating point
