Preemptive cache writeback with transaction support

A method of preemptive cache writeback includes transmitting, from a first cache controller of a first cache to a second cache controller of a second cache, an unused bandwidth message representing an unused bandwidth between the first cache and the second cache during a first cycle. During a second cycle, a cache line containing dirty data is preemptively written back from the second cache to the first cache based on the unused bandwidth message. Further, the cache line in the second cache is written over in response to a cache miss to the second cache.

Virtual FPGA management and optimization system

A macro scheduler includes a resource tracking module configured to update a database enumerating a plurality of macro components of a set of field programmable gate array (FPGA) devices, a communication interface configured to receive from a first client device a first design definition indicating one or more specified macro components for a design, resource allocation logic configured to allocate a first set of macro components for the design by allocating one of the plurality of macro components for each of the one or more specified macro components indicated in the first design definition, and configuration logic configured to implement the design in the set of FPGA devices by configuring the first set of allocated macro components according to the first design definition.
