摘要： A return stack buffer mechanism that uses two separate return stack buffers is disclosed. The first return stack buffer is the Speculative Return Stack Buffer. The Speculative Return Stack Buffer is updated using speculatively fetched instructions. Thus, the Speculative Return Stack Buffer may become corrupted when incorrect instructions are fetched. The second return stack buffer is the Actual Return Stack Buffer. The Actual Return Stack Buffer is updated using information from fully executed branch instructions. When a branch misprediction causes a pipeline flush, the contents of the Actual Return Stack Buffer is copied into the Speculative Return Stack Buffer to correct any corrupted information.

摘要： Some virtual memory systems allow more that one memory page size. To quickly translate virtual page addresses into physical page addresses, a multi-page size translation look-aside buffer is needed. The multi-page size translation look-aside buffer has a virtual address array and a physical address array. The virtual address array has a set of virtual address entries that are compared to a received virtual address. The virtual address array entries have virtual address tag field, a valid bit, and a page size bit. The page size bit defines the size of the memory page and thus defines the number of bits in the virtual address that must be matched with virtual address tag bits in the virtual address array. The valid bit indicates if the entry is valid or not. When a hit is detected in the virtual address array, a corresponding entry in the physical address array is activated. The physical address array comprises a physical page address and a set of page attributes. The physical address array also has a locked bit and an access bit that are used to implement a translation look-aside buffer replacement scheme.
摘要翻译：一些虚拟内存系统允许更多的一个内存页面大小。为了将虚拟页面地址快速翻译成物理页面地址，需要一个多页面大小的翻译后备缓冲区。多页大小翻译后备缓冲区具有虚拟地址阵列和物理地址阵列。虚拟地址阵列具有与接收的虚拟地址进行比较的一组虚拟地址条目。虚拟地址阵列条目具有虚拟地址标记字段，有效位和页大小位。页面大小位定义存储器页面的大小，从而定义虚拟地址中必须与虚拟地址数组中的虚拟地址标记位匹配的位数。有效位表示条目是否有效。当在虚拟地址阵列中检测到命中时，物理地址阵列中的相应条目被激活。物理地址阵列包括物理页面地址和一组页面属性。物理地址阵列还具有用于实现翻译后备缓冲器替换方案的锁定位和访问位。

摘要： A Branch Target Buffer Circuit in a computer processor that predicts branch instructions within a stream of computer instructions is disclosed. The Branch Target Buffer Circuit uses a Branch Target Buffer Cache with multiple BTB banks that store branch information about previously executed branch instructions. The branch information stored in each bank of the Branch Target Buffer Cache is addressed by the last byte of each branch instruction When an Instruction Fetch Unit in the computer processor fetches a block of instructions it sends the Branch Target Buffer Circuit an instruction pointer. Based on the instruction pointer, the Branch Target Buffer Circuit looks in the Branch Target Buffer Cache banks to see if any of the instructions in the block being fetched is a branch instruction. When the Branch Target Buffer Circuit finds an upcoming branch instruction in the Branch Target Buffer Cache, the Branch Target Buffer Circuit informs an instruction Fetch Unit about the upcoming branch instruction.

摘要： An improvement in a microprocessor having a cache memory providing strong and weak write ordering modes. The microprocessor includes a terminal for receiving a signal indicating whether an external write buffer is empty and an internal signal indicating whether an internal write buffer is empty. Operation of the microprocessor is halted in the strong ordering mode if the write buffers are not empty and a hit condition occurs during a write cycle until the buffers are empty.

摘要： An improvement in a microprocessor permitting the selection of write-back, write-through or write-once protocols is disclosed. A pin is connected to either ground or Vcc potential to select either the write-through or write-back protocols. When this pin is connected to the read/write line, the write-once protocol is selected. Interconnection between two processors is described which permits the processors to operate in a write-once protocol with a minimum of glue logic.

摘要： A processor may include an instruction decoder to decode macroinstructions into micro-operations. In some embodiments, the instruction decoder may include a first decoder and a second decoder. The first decoder may decode a macroinstruction having SSE data type operands into a laminated micro-operation, and may generate unlamination information for the laminated micro-operation. The second decoder may generate from the laminated micro-operation and the unlamination information two or more micro-operations, where operands of the two or more micro-operations each correspond to a half of one of the SSE operands of the macroinstruction.
