摘要： In an embodiment, memory access requests for information stored within a system memory pass through an integrated circuit. The system memory may include a micro-architectural memory region to store instructions and/or data, where the micro-architectural memory region is to be exclusively accessible by a micro-architectural agent The integrated circuit may include memory access director to direct memory access requests to the micro-architectural memory region if the memory access director determines that the memory access request includes a location within the at least one micro-architectural memory region and the micro-architectural agent is operating in a micro-architectural memory region access mode.

摘要： An apparatus, method, machine-readable medium, and system are disclosed. In one embodiment the apparatus is a micro-page table engine that includes logic that is capable of receiving a memory page request for a page in global memory address space. The apparatus also includes a translation lookaside buffer (TLB) that is capable of storing one or more memory page address translations. Additionally, the apparatus also has a page miss handler capable of performing a micro physical address lookup in a page miss handler tag table in response to the TLB not storing the memory page address translation for the page of memory referenced by the memory page request. The apparatus also includes memory management logic that is capable of managing the page miss handler tag table entries. The micro-page table engine allows the TLB to be an agent that determines whether data in a two-level memory hierarchy is in a hot region of memory or in a cold region of memory. When data is in the cold region of memory, the micro-page table engine fetches the data to the hot memory and a hot memory block is then pushed out to the cold memory area.

摘要： Method, apparatus, and system for a programmable event driven yield mechanism that may activate other threads. The yield mechanism may allow triggering of a service thread that may execute currently with a main thread upon occurrence of an architecturally-defined condition. The service thread may be activated, in response to the condition, with limited intervention of an operating system. In one embodiment, an apparatus includes execution resources to execute a plurality of instructions and a monitor to detect an architecturally-defined condition. The apparatus may include an event handler to handle a yield event generated when the architecturally-defined condition has been detected. An architectural mechanism, including processor instructions and channel registers, may be utilized to allow user-level code to enable the yield event mechanism. Other embodiments are also described and claimed.

摘要： An instruction locking apparatus and method for a cache memory allowing execution time predictability and high speed performance. The present invention implements a cache locking scheme in a two set associative instruction cache that utilizes a specially designed Least Recently Used (LRU) unit to effectively lock a first portion of the instruction cache to allow high speed and predictable execution time for time critical program code sections residing in the first portion while leaving another portion of the instruction cache free to operate as an instruction cache for other, non-critical, code sections. The present invention provides the above features in a system that is virtually transparent to the program code and does not require a variety of complex or specialized instructions or address coding methods. The present invention is flexible in that the two set associative instruction cache is transformed into what may be thought of as a static RAM in cache, and in addition, a direct map cache unit. Several different time critical code sections may be loaded and locked into the cache at different times.
摘要翻译：一种用于缓存的指令锁定装置和方法，其允许执行时间可预测性和高速性能。本发明在两组关联指令高速缓冲存储器中实现高速缓存锁定方案，其利用专门设计的最近使用（LRU）单元来有效地锁定指令高速缓存的第一部分，以允许用于时间关键程序代码的高速度和可预测的执行时间驻留在第一部分中的部分，同时使指令高速缓存的另一部分可自由地作为用于其他非关键代码段的指令高速缓存。本发明在系统中提供对程序代码实际上是透明的并且不需要各种复杂或专门的指令或地址编码方法的上述特征。本发明的灵活性在于，将两组关联指令高速缓存转换成可以被认为是高速缓存中的静态RAM的内容，另外还有直接映射缓存单元。可以在不同的时间将几个不同的时间关键代码段加载并锁定到高速缓存中。
