CORDIC Coprocessor
The CORDIC Coprocessor provides CPU with hardware support for the solving of
circular (trigonometric), linear (multiply-add, divide-add) and hyperbolic functions.
Features
Modes of operation
– Supports all CORDIC operating modes for solving circular (trigonometric), linear
(multiply-add, divide-add) and hyperbolic functions
– Integrated look-up tables (LUTs) for all operating modes
Circular vectoring mode: Extended support for values of initial X and Y data up to full
range of [-215,(215-1)] for solving angle and magnitude
Circular rotation mode: Extended support for values of initial Z data up to full range
of [-215,(215-1)], representing angles in the range [-
π,((215-1)/215)π] for solving
trigonometry
Implementation-dependent operational frequency of up to 80 MHz
Gated clock input to support disabling of module
16-bit accessible data width
– 24-bit kernel data width plus 2 overflow bits for X and Y each
– 20-bit kernel data width plus 1 overflow bit for Z
– With KEEP bit to retain the last value in the kernel register for a new calculation
16 iterations per calculation: Approximately 41 clock-cycles or less, from set of start
(ST) bit to set of end-of-calculation flag, excluding time taken for write and read
access of data bytes.
Twos complement data processing
– Only exception: X result data with user selectable option for unsigned result
X and Y data generally accepted as integer or rational number; X and Y must be of
the same data form
Entries of LUTs are 20-bit signed integers
– Entries of atan and atanh LUTs are integer representations (S19) of angles with
the scaling such that [-215,(215-1)] represents the range [-
π,((215-1)/215)π]
– Accessible Z result data for circular and hyperbolic functions is integer in data form
of S15
Emulated LUT for linear function
– Data form is 1 integer bit and 15-bit fractional part (1.15)
– Accessible Z result data for linear function is rational number with fixed data form
of S4.11 (signed 4Q16)
Truncation Error
– The result of a CORDIC calculation may return an approximation due to truncation
of LSBs
– Good accuracy of the CORDIC calculated result data, especially in circular mode
Interrupt
– On completion of a calculation
