Should Be Zero (SBZ)
Write as 0, or all 0s for bit fields, by software. Writing as 1 produces
Unpredictable results.
Should
Be
Zero
or
Preserved (SBZP)
Write as 0, or all 0s for bit fields, by software, or preserved by writing the
same value back that has been previously read from the same field on the
same processor.
Thread-safe
In a multi-tasking environment, thread-safe functions use safeguard
mechanisms when accessing shared resources, to ensure correct operation
without the risk of shared access conflicts.
Thumb instruction
One or two halfwords that specify an operation for a processor to perform.
Thumb instructions must be halfword-aligned.
Unaligned
A data item stored at an address that is not divisible by the number of bytes
that defines the data size is said to be unaligned. For example, a word stored
at an address that is not divisible by four.
Undefined
Indicates an instruction that generates an Undefined instruction exception.
Unpredictable (UNP)
You cannot rely on the behavior. Unpredictable behavior must not represent
security holes. Unpredictable behavior must not halt or hang the processor,
or any parts of the system.
Warm reset
Also known as a core reset. Initializes the majority of the processor excluding
the debug controller and debug logic. This type of reset is useful if you are
using the debugging features of a processor.
WA
See Write-allocate.
WB
See Write-back.
Word
A 32-bit data item.
Write
Writes are defined as operations that have the semantics of a store. Writes
include the Thumb instructions STM, STR, STRH, STRB, and PUSH.
Write-allocate (WA)
In a write-allocate cache, a cache miss on storing data causes a cache line
to be allocated into the cache.
Write-back (WB)
In a write-back cache, data is only written to main memory when it is forced
out of the cache on line replacement following a cache miss. Otherwise,
writes by the processor only update the cache. This is also known as
copyback.
Write buffer
A block of high-speed memory, arranged as a FIFO buffer, between the
data cache and main memory, whose purpose is to optimize stores to main
memory.
Write-through (WT)
In a write-through cache, data is written to main memory at the same time
as the cache is updated.
