The controlling apparatus for an industrial product of this disclosure has a couple of microcomputers each of which has a CPU and a memory and each of which runs the same controlling program as well as the same diagnostic program sequence parallelly and simultaneously. After the CPU of the microcomputer writes the calculated result of the diagnostic program sequence in the predetermined area of the storing area for monitoring value, such CPU send the same calculated result to the other one of the microcomputers (receiving microcomputer). The CPU of the receiving microcomputer makes a diagnosis for finding whether or not the received result is identical with its own calculated result.

A method for a controller to execute a program comprising a sequence of functions on an accelerator with a pipelined architecture comprising a microcode buffer. The method comprises executing a function of the program as a sequence of operations, wherein the sequence of operations is represented by a sequence of templates, determining whether the template is non-colliding with previously inserted templates in the microcode buffer, determining whether data in local memory will be referenced before all previously inserted templates have taken effect, determining whether registers will be referenced before all previously inserted templates in the microcode buffer have taken effect, when it is determined that the template fits, that resources are available, that local data memory accesses will not collide, and that register accesses will not collide: creating a sequence of microcode instructions in the template, and inserting the template into the microcode buffer.

An embodiment method executes instructions, each corresponding to switching a signal, a delay, and a condition selected among first, second, or third conditions. Each execution includes performing, after the delay, switching the signal if the condition is the first condition, if the condition is the second condition and a flag is in an active state, or if the condition is the third condition and the flag is in an inactive state, or not switching the signal if the condition is the second condition and the flag is in the inactive state, or if the condition is the third condition and the flag is in the active state. A first instruction represents a first switching of a first signal, a first delay, and the second condition, and is immediately followed by a second instruction representing the first switching of the first signal, a second delay, and the third condition.

A processor includes a micro-operation cache having a plurality of micro-operation cache entries for storing micro-operations decoded from instruction groups and a micro-operation filter having a plurality of micro-operation filter table entries for storing identifiers of instruction groups for which the micro-operations are predicted dead on fill if stored in the micro-operation cache. The micro-operation filter receives an identifier for an instruction group. The micro-operation filter then prevents a copy of the micro-operations from the first instruction group from being stored in the micro-operation cache when a micro-operation filter table entry includes an identifier that matches the first identifier.

Systems and methods are disclosed for scheduling threads on a processor that has at least two different core types, such as an asymmetric multiprocessing system. Each core type can run at a plurality of selectable voltage and frequency scaling (DVFS) states. Threads from a plurality of processes can be grouped into thread groups. Execution metrics are accumulated for threads of a thread group and fed into a plurality of tunable controllers for the thread group. A closed loop performance control (CLPC) system determines a control effort for the thread group and maps the control effort to a recommended core type and DVFS state. A closed loop thermal and power management system can limit the control effort determined by the CLPC for a thread group, and limit the power, core type, and DVFS states for the system. Deferred interrupts can be used to increase performance.

Systems, apparatuses, and methods related to a block-based processor core composition register are disclosed. In one example of the disclosed technology, a processor can include a plurality of block-based processor cores for executing a program including a plurality of instruction blocks. A respective block-based processor core can include one or more sharable resources and a programmable composition control register. The programmable composition control register can be used to configure which resources of the one or more sharable resources are shared with other processor cores of the plurality of processor cores.

Techniques are provided for enabling cross-process coordination between multiple instances of given microservice in a cloud computing system. A method includes running a plurality of active instances of a given microservice of a computing system comprising a distributed microservices architecture. A first active instance of the plurality of active instances executes a portion of program code of the given microservice to perform a job. The portion of the program code of the given microservice includes an instance synchronization element which is configured to enable cross-process coordination between the plurality of active instances of the given microservice with the support of a collaboration service. The first active instance utilizes the instance synchronization element to communicate with the collaboration service and cause the collaboration service to execute a process associated with the instance synchronization element to thereby implement the cross-process coordination between the plurality of active instances for executing the job.

The present disclosure includes apparatuses and methods related to microcode instructions indicating instruction types. One example apparatus comprises a memory storing a set of microcode instructions. Each microcode instruction of the set can comprise a first field comprising a number of control data units, and a second field comprising a number of type select data units. Each microcode instruction of the set can have a particular instruction type defined by a value of the number of type select data units, and particular functions corresponding to the number of control data units are variable based on the particular instruction type.

A 3D NAND memory device is provided in which control is performed by two microcontroller units (MCU). During manufacture of the memory device, bug fixes required for the controller may be addressed using a software solution by which an instruction requiring correction in one of the two MCUs is replaced with a corrected instruction stored in a RAM.
