MaverickCrunch Co-Processor
EP93xx User’s Guide
The co-processor performs the following standard operations on all four supported data
formats:
In addition, for 32-bit integers, the co-processor provides:
Any of the four data formats may be converted to another of the formats. All four data types
may be loaded directly from and stored directly to memory via the ARM920T co-processor
interface. They may also be moved to or from ARM920T registers.
The MaverickCrunch co-processor also provides a 72-bit extended precision integer format
that is used only in the accumulators. The accumulators may also be used in MAC and MSB
operations.
IEEE-754 rounding and exceptions are also provided. Four rounding modes for floating point
operations are:
Exceptions include:
• IEEE-754 single precision floating point (24-bit signed significand and 8-bit biased
• IEEE-754 double precision floating point (53-bit signed significand and 11-bit biased
• 32-bit integer
• 64-bit integer
• addition
• subtraction
• multiplication
• absolute value
• negation
• logical left/right shift
• comparison
• multiply-accumulate (MAC)
• multiply-subtract (MSB)
• round to nearest
• round toward
• round toward
• round toward 0
• Invalid operator
• Overflow
• Underflow
