International Classification:

G06F 13/28

US Classification:

710 23, 711118, 711135, 711141

Abstract:

Methods and apparatuses are disclosed for direct access to cache memory. Embodiments include receiving, by a direct access manager that is coupled to a cache controller for a cache memory, a region scope zero command describing a region scope zero operation to be performed on the cache memory; in response to receiving the region scope zero command, generating a direct memory access region scope zero command, the direct memory access region scope zero command having an operation code and an identification of the physical addresses of the cache memory on which the operation is to be performed; sending the direct memory access region scope zero command to the cache controller for the cache memory; and performing, by the cache controller, the direct memory access region scope zero operation in dependence upon the operation code and the identification of the physical addresses of the cache memory.

International Classification:

G06F 9/30

US Classification:

712208, 712E09028

Abstract:

A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design for forwarding store data to loads in a pipelined processor is provided. In one implementation, a processor is provided that includes a decoder operable to decode an instruction, and a plurality of execution units operable to respectively execute a decoded instruction from the decoder. The plurality of execution units include a load/store execution unit operable to execute decoded load instructions and decoded store instructions and generate corresponding load memory operations and store memory operations. The store queue is operable to buffer one or more store memory operations prior to the one or more memory operations being completed, and the store queue is operable to forward store data of the one or more store memory operations buffered in the store queue to a load memory operation on a byte-by-byte basis.

US Classification:

711118, 710107, 711E12017

Abstract:

An L2 cache, method and computer program product for transferring an inbound bus operation to a processor side handling machine. The method includes a bus operation handling machine accepting the inbound bus operation received over a system interconnect, the bus operation handling machine identifying a demand operation of the processor side handling machine that will complete the bus operation, the bus operation handling machine sending the identified demand operation to the processor side handling machine, and the processor side handling machine performing the identified demand operation.

International Classification:

G06F 21/24

US Classification:

726 27

Abstract:

Acquiring access to a token controlled system resource, including: receiving, by a token broker, a command that requires access to the token controlled system resource, where the token broker is automated computing machinery for acquiring tokens and distributing the command to the token controlled system resource for execution; identifying, by the token broker, a first need state, the first need state indicating that the token broker requires access to the token controlled system resource to which the token broker does not possess a token; requesting, by the token broker, a configurable number of tokens to gain access to the token controlled system resource, without dispatching an operation handler for executing the command until at least one token is acquired; assigning, by the token broker, an acquired token to the operation handler; and dispatching, by the token broker, the operation handler and its assigned token for executing the command.

International Classification:

G06F 12/08

US Classification:

711145, 711E12032

Abstract:

One embodiment provides a cached memory system including a memory cache and a plurality of read-claim (RC) machines configured for performing read and write operations dispatched from a processor. According to control logic provided with the cached memory system, a hazard is detected between first and second read or write operations being handled by first and second RC machines. The second RC machine is suspended and a subset of the address bits of the second operation at specific bit positions are recorded. The subset of address bits of the first operation at the specific bit positions are broadcast in response to the first operation being completed. The second operation is then re-requested.

US Classification:

435325, 422527

Abstract:

A system and method for isolating and separating lipoaspirate particles. The system includes a generally cylindrical container having a lid and a bottom wherein the container includes at least one input port positioned to permit a lipoaspirate fluid to enter the container above the bottom; and a source of a vacuum coupled to the container to provide a partial vacuum during use of the system.
