摘要： Mechanisms are provided for performing a floating point arithmetic operation in a data processing system. A plurality of floating point operands of the floating point arithmetic operation are received and bits in a mantissa of at least one floating point operand of the plurality of floating point operands are shifted. One or more bits of the mantissa that are shifted outside a range of bits of the mantissa of at least one floating point operand are stored and a vector value is generated based on the stored one or more bits of the mantissa that are shifted outside of the range of bits of the mantissa of the at least one floating point operand. A resultant value is generated for the floating point arithmetic operation based on the vector value and the plurality of floating point operands.

摘要： An apparatus for providing system memory usage throttling within a data processing system having multiple chiplets is disclosed. The apparatus includes a system memory, a memory access collection module, a memory credit accounting module and a memory throttle counter. The memory access collection module receives a first set of signals from a first cache memory within a chiplet and a second set of signals from a second cache memory within the chiplet. The memory credit accounting module tracks the usage of the system memory on a per user virtual partition basis according to the results of cache accesses extracted from the first and second set of signals from the first and second cache memories within the chiplet. The memory throttle counter for provides a throttle control signal to prevent any access to the system memory when the system memory usage has exceeded a predetermined value.

摘要： According to one aspect of the present disclosure a method and technique for monitoring memory access is disclosed. The method includes monitoring, by a plurality of memory controllers, access to a memory unit, wherein each memory controller is associated with a different range of memory addresses of the memory unit, and wherein each memory controller monitors access for its associated range of memory addresses. The method also includes updating an incrementor with access data corresponding to accesses to the memory unit, wherein each memory controller updates the access data based on access of its associated range of memory addresses. The method further includes storing, by each respective memory controller, the updated access data in a cache corresponding to the respective range of memory addresses and, responsive to the updated access data for a respective range of memory addresses exceeding a threshold, storing the access data for the respective range of memory addresses in memory unit.
