Embodiment Construction

[0115] Reference is made to the detailed description of the embodiments in the drawings. While several embodiments are described in association with icons, there is no limitation therein to the disclosed embodiments or the purpose of the disclosed embodiments. On the contrary, the intention is to cover all alternatives, modifications and equivalents.

[0116] Most computer systems use cache memory, which is small, fast memory that records recently accessed data. Typically, cache memory is used to increase the speed of accessing the same data.

[0117] Usually, when data is read or written, the main memory also backs up the associated memory address in the cache memory. The cache memory monitors whether the address at which data is to be read next is already present in the cache memory. If the data is already in cache memory (called a "cache hit") then immediately tell main memory to cancel the read action. If the data is not in cache memory (called a "cache miss") then the...

Abstract

The present disclosure relates to caches that are capable of improving processor performance. In some embodiments, among others, incoming requests are compared to determine whether or not those requests match. In the event that the incoming requests match, the matching requests are merged. For other embodiments, an incoming request is compared to a previous entry to determine whether the request matches the entry. In the event that the request matches the entry, the request and the entry are merged. These entries may originate from the same cache line, or, alternatively, may originate from different cache lines.

Description

technical field [0001] The present invention relates to processors, and more particularly to cache memories associated with processors. Background technique [0002] The increasing complexity of software applications, such as image processing, has increased the demand for hardware processing capabilities. Some current processing architectures include one or more cache memories to improve processing efficiency. Contrast with main memory - located outside the processor; cache memory is part of the processor's processing unit. Thus; allowing faster data access and, consequently, faster processing speeds. [0003] Various cache memory structures have been developed, but there is still much room for improvement in these structures. Contents of the invention [0004] The present invention relates to cache memories that improve processor performance. In some embodiments, newly entered requirements are compared to determine if they match. If they match, those matching require...
