Bit Description
8 High Priority Stream Throttling Enable:
Normally High Priority Streams are not Throttled when either the counter based mechanism or
Thermal Sensor mechanism demands Throttling.
0 = Normal operation.
1 = Block High priority streams during Throttling.
7:0 Global DDR SDRAM Sampling Window (GDSW): This 8-bit value is multiplied by 4 to define the
length of time in milliseconds (0–1020) over which the number of Octal Words (16 bytes) Read/Written
is counted and Throttling is imposed. Note that programming this field to 00h disables system memory
throttling.
Recommended values are between 0.25 and 0.75 seconds.
