Abstract
An example system includes a plurality of execution units, a shared resource, and an allocation control circuit. Each execution unit may generate a resource allocation request that includes a resource allocation size. The allocation control circuit may select a particular resource allocation request from the plurality of resource allocation requests, and determine an availability, based on an allocation register, of contiguous resource blocks within the shared resource. In response to determining that a number of the contiguous resource blocks satisfies a requested allocation size, the allocation control circuit may select an address corresponding to a particular resource block of the one or more contiguous resource blocks, and allocate the resource blocks to a corresponding execution unit. In response to a beginning of a second system clock cycle, the allocation control circuit may also update the allocation register based on the selected address and the requested allocation size.
