This Cache module provides ARP32 family-specific implementations of the
APIs defined in
ICache. It also
provides additional ARP32 specific cache functions.
enum Cache_Type |
|
Lists of bitmask cache types
typedef enum Cache_Type {
Cache_Type_L1P,
// Level 1 Program cache
Cache_Type_L1D,
// Level 1 Data cache
Cache_Type_L1,
// Level 1 caches
Cache_Type_L2P,
// Level 2 Program cache
Cache_Type_L2D,
// Level 2 Data cache
Cache_Type_L2,
// Level 2 caches
Cache_Type_ALLP,
// All Program caches
Cache_Type_ALLD,
// All Data caches
Cache_Type_ALL
// All caches
} Cache_Type;
config Cache_A_byteCountTooLarge // module-wide |
|
Assert raised when byte count is too large
extern const Assert_Id Cache_A_byteCountTooLarge;
Cache_disable() // module-wide |
|
Disables the 'type' cache(s)
Void Cache_disable(Bits16 type);
ARGUMENTS
type
bit mask of Cache type
Cache_enable() // module-wide |
|
Enables all cache(s)
Void Cache_enable(Bits16 type);
ARGUMENTS
type
bit mask of Cache type
Cache_inv() // module-wide |
|
Invalidate the range of memory within the specified starting
address and byte count. The range of addresses operated on
gets quantized to whole cache lines in each cache. All lines
in range are invalidated for all the 'type' caches
Void Cache_inv(Ptr blockPtr, SizeT byteCnt, Bits16 type, Bool wait);
ARGUMENTS
blockPtr
start address of range to be invalidated
byteCnt
number of bytes to be invalidated
type
bit mask of Cache type
wait
wait until the operation is completed
Cache_invL1pAll() // module-wide |
|
Invalidate all of L1 Program cache
DETAILS
Performs a global invalidate of L1P cache.
Polls the L1P invalidate register until operation is complete.
Cache_invL1pSingleAddr() // module-wide |
|
Invalidate a single address in L1 Program Cache
Void Cache_invL1pSingleAddr(Ptr blockPtr);
Cache_preloadL1p() // module-wide |
|
Preload the L1 Program cache range
Void Cache_preloadL1p(Ptr blockPtr, SizeT byteCnt);
Cache_wait() // module-wide |
|
Wait for a previous cache operation to complete
DETAILS
Wait for the cache wb/wbInv/inv operation to complete. A cache
operation is not truly complete until it has worked its way
through all buffering and all memory writes have landed in the
source memory.
Cache_wb() // module-wide |
|
Writes back a range of memory from all cache(s)
Void Cache_wb(Ptr blockPtr, SizeT byteCnt, Bits16 type, Bool wait);
ARGUMENTS
blockPtr
start address of range to be invalidated
byteCnt
number of bytes to be invalidated
type
bit mask of Cache type
wait
wait until the operation is completed
DETAILS
Writes back the range of memory within the specified starting
address and byte count. The range of addresses operated on
gets quantized to whole cache lines in each cache. All lines
within the range are left valid in the 'type' caches and the data
within the range will be written back to the source memory.
Cache_wbAll() // module-wide |
|
Write back all caches
DETAILS
Perform a global write back. There is no effect on program cache.
All data cache lines are left valid.
Cache_wbInv() // module-wide |
|
Writes back and invalidates the range of memory within the
specified starting address and byte count. The range of
addresses operated on gets quantized to whole cache lines in
each cache. All lines within the range are written back to the
source memory and then invalidated for all 'type' caches
Void Cache_wbInv(Ptr blockPtr, SizeT byteCnt, Bits16 type, Bool wait);
ARGUMENTS
blockPtr
start address of range to be invalidated
byteCnt
number of bytes to be invalidated
type
bit mask of Cache type
wait
wait until the operation is completed
Cache_wbInvAll() // module-wide |
|
Write back invalidate all caches
DETAILS
Performs a global write back and invalidate. All cache lines
are written out to physical memory and then invalidated.
