S
short floating-point format:
A 16-bit representation of a floating point num-
ber with a 12-bit mantissa and a 4-bit exponent.
short floating-point format for external 16-bit data:
A 16-bit representa-
tion of a floating point number with an 8-bit mantissa and an 8-bit expo-
nent.
short integer format:
A 2s-complement,16-bit format for integer data.
short unsigned-integer format:
A 16-bit unsigned format for integer data.
sign-extend:
The process of filling the high-order bits of a number with the
sign bit.
single-precision floating-point format:
A 32-bit representation of a float-
ing-point number with a 24-bit mantissa and an 8-bit exponent.
single-precision integer format:
A 2s-complement 32-bit format for inte-
ger data.
single-precision unsigned-integer format:
A 32-bit unsigned format for
integer data.
software interrupt:
An interrupt caused by the execution of a TRAP instruc-
tion.
ST:
See status register.
stack:
A block of memory reserved for storing and retrieving data on a first-in
last-out basis. It is usually used for storing return addresses and for pre-
serving register values.
status register:
A register in the CPU register file that contains global in-
formation relating to the current state of the CPU.
T
timer:
A programmable peripheral that generates pulses for timed events.
timer-period register:
A 32-bit memory-mapped register that specifies the
period for the on-chip timer.
