摘要： A method is disclosed for instructing a computing system to ensure that a line is present in an instruction cache that includes selecting a line-touch instruction, recognizing the line-touch instruction as a type of branch instruction where the branch is not taken, executing the line-touch instruction to fetch a target line from a target address into the instruction cache, and interlocking the execution of the line-touch instruction with the completion of the fetch of the target line in order to prevent execution of the instruction following the line-touch instruction until after the target line has reached the cache.

摘要： Complex floating point instructions are executed under millicode control when it is not cost effective to implement its function in hardware. One of the disadvantages to executing complex instructions using millicode routines is that determining and accessing the instructions operands are costly for millicode performance. To determine what the source and target location are, the instruction text is parsed. Furthermore the millicode instruction stream must be modified to access the operand data from and write the result to the program registers specified by the complex floating point instruction. The invention overcomes these disadvantages by providing millicode with register indirect access to the program floating point registers.
摘要翻译：当在硬件中实现其功能不具有成本效益时，复杂的浮点指令在毫秒控制下执行。使用millicode例程执行复杂指令的一个缺点是确定和访问指令操作数对于millicode性能来说是昂贵的。要确定源和目标位置是什么，解释说明文本。此外，必须修改millicode指令流以访问操作数数据，并将结果写入由复杂浮点指令指定的程序寄存器。本发明通过向编程浮点寄存器提供寄存器间接访问的毫代码来克服这些缺点。

摘要： A read only storage (ROS) array holds a small set of relatively simple millicode instructions; those millicode instruction routines which are most commonly called on in executing common application workloads. The millicode read only store is implemented as a portion of hardware system area (HSA) storage. The cache control includes a register which contains hardware system area address corresponding to the read only store address. When an instruction fetch request is received by the cache control, the absolute address of the instruction fetch request is compared with the read only store address in the register in parallel with the normal cache directory lookup. If the instruction fetch request matches the read only store address, the fetch is made from the read only store independently of the directory lookup result.

摘要： An exemplary embodiment of the invention is a method and system for managing a result returned from a translator co-processor to a recovery unit of a central processor. The computer system has a pipelined computer processor and a pipelined central processor, which executes an instruction set in a hardware controlled execution unit and executes an instruction set in a milli-mode architected state with a millicode sequence of instructions in the hardware controlled execution unit. The central processor initiates a request to the translator co-processor a cycle after decode of a perform translator operation instruction in the millicode sequence. The translator co-processor processes the perform translator operation instruction to generate a perform translator operation result. The translator co-processor returns the results to a recovery unit of the central processor. The recovery unit stores the perform translator operation result in a system register. The request for the perform translator operation result by the central processor is interlocked by a hardware interlock of the recovery unit until the translator co-processor returns the perform translator operation result. The mechanism allows the recovery unit to maintain the correct perform translator operation result with speculative execution and instruction level retry recovery throughout the duration of the perform translator operation.

摘要： A range check instruction sequence, which performs a logical comparison between two 32-bit values and updates the condition code as a result. It operates identically to the ESA/390 instruction compare logical (CLR) except for the way in which the condition code is set. The new condition code is a function of both the comparison result and the previous condition code. If the first operand is greater than the second operand, the condition code remains unchanged. If the first operand is less than or equal to the second operand, the condition code is set to 2 if it was previously 0 or 1, and is set to 3 if it was previously 2 or 3. This may be understood as advancing the state of the condition code among the groups (0,1), 2, and 3 if the first operand is not greater than the second operand.

摘要： An exemplary embodiment of the present invention is a method and system for reducing the number of branch instructions required to test combinations of millicode branch points. The method is implemented via a pipe-lined computer processor executing a millicode routine. The processor interrogates a millicode condition code; interrogates a first field of the TMBP instruction, the results of which determine a logical function to be performed on the millicode condition code; interrogates a second field of the TMBP instruction which specifies a first millicode branch point; interrogates a third field of the TMBP instruction, which specifies a second millicode branch point; and sets a millicode condition code based upon the results of the interrogating and used for executing subsequent TMBP instructions or conditional branch instructions.
