operations that yield single-precision results , then the two register ﬁles are completely de-

coupled - thus effectively doubling the amount of registers available for the data ALU.

4.1 CHANGE TO THE PROGRAMMING MODEL (SINGLE PRECISION MODE)

To suppor t the single precision mode, bit 5 of the OMR suppor ts a new single precision

mode (SPM) bit. When OMR bit 5 is clear, the single precision mode is disabled. When

OMR bit 5 is set, the processor is in the single precision mode. The SPM bit is cleared

during reset.

4.2 SINGLE PRECISION MODE DETAILS

The processor suppor ts the following three measures to achieve the Data-ALU Register

File decoupling when it is in single precision mode:

1. Single-precision MOVE operations affect the high and middle portion of the destination

2. Data-ALU ﬂoating-point operations that yield single-precision results affect the high

and middle portion of the destination register. They DO NOT clear the low portion of

the destination register.

3. Integer multiply operations (MPYS and MPYU) yield 64-bit results (from the condition

code’s point of view) of which only the 32 least signiﬁcant bits are written into the low

portion of the destination register. The middle portion of the destination register is not

aff ected. Thus, the implication is that the largest tw o integers that can be m ultiplied in

this mode without a loss of signiﬁcant digits is 16. If you are using the integer m ultiply

operation MPYS f or the m ultiplication of 16-bit numbers , you m ust sign-e xtend the up-

per 16 bits of the multiplicand and the multiplier to get a valid integer result.

These measures assure that a single-precision ﬂoating-point operation or a MOVE does

not overwrite an integer variable stored in the low portion of the destination register. Fur-

thermore these measures assure that an integer multiply does not o v erwrite a single-pre-

cision ﬂoating-point number stored in the high and middle portions of the destination

Single Precision Mode does not affect double-precision MOVE operations, long integer

MOVE operations or the single-extended-precision ﬂoating-point operations.
