Standard Artesyn Functions 10-59
0002M621-15
The function MemReset sets the free memory pool to the empty state. This
function must be called once for every reset operation and before the mem-
ory management facilities can be used. It is also necessary to call this func-
tion before every call to
MemAdd .
The function MemAdd initializes the free memory pool to use the memory
starting at MemAddr of size specified by MemSize . This function currently
allows for only one contiguous memory pool and must be preceded by a
function call to
MemReset .
The function MemStats monitors memory usage. This function outputs a
table showing how much memory is available and how much is used and lost
as a result of overhead.

SYNOPSIS
unsigned char *MemTop(void)
unsigned char *MemBase(void)
DESCRIPTION
This is a collection of miscellaneous board support functions.
The functions MemTop and MemBase are used to determine the addresses
of the last and first long words in free memory. The size of DRAM is deter-
mined by bits DH(0:3) of the Board Configuration register (FF00,0600
16
). The
base of free memory is determined by the compiler-created variable End ,
which indicates the end of the monitor’s bss section.
