Abstract: A processor of an aspect is to perform operations corresponding to an unsigned integer multiply-accumulate instruction. The unsigned integer multiply-accumulate instruction is to indicate a first unsigned integer, a second unsigned integer, a first register that is have a third unsigned integer, and a second register. The operations include to multiply the first unsigned integer and the second unsigned integer to generate a product and add the product and the third unsigned integer to generate a sum. The operations also include to store a first portion of the sum in the second register. The first portion of the sum includes M least significant bits of the sum. The operations also include to store a second portion of the sum in the first register. The second portion of the sum includes all bits of the sum that are more significant than the M least significant bits. Other processors are also disclosed.

Abstract: Embodiments are generally directed to methods and apparatuses for dynamically changing data priority in a cache. An embodiment of an apparatus comprising: a priority controller to: receive a memory access request to request data; and set a priority flag for the memory access request based on an accumulated access amount of data stored in a memory block to be accessed by the memory access request to dynamically change a priority level of the requested data.

Abstract: An embodiment of an electronic apparatus may comprise one or more substrates and a controller coupled to the one or more substrates, the controller including circuitry to identify failed memory regions in a memory by a rank, bank, and device associated with the failed memory region, and provide recovery for failed memory regions in three or more banks of a first rank of the memory or three or more devices of the first rank of the memory by virtual lock step device data correction with one or more other ranks of the memory. Other embodiments are disclosed and claimed.

Abstract: An optical line terminal and a method for upgrading a primary device and a secondary device of the optical line terminal are provided. The secondary device receives a stepwise reset notification sent by the primary device; the secondary device resets a control chip according to the received stepwise reset notification, and sends a request message to the primary device after the control chip is reset, where the request message is used to request the primary device to deliver new configuration data; the secondary device obtains the new configuration data delivered by the primary device; and the secondary device restores data of the control chip by using the new configuration data delivered by the primary device. In the embodiments of the present disclosure, only the control chip of the secondary device needs to be reset and upgraded, and other hardware structures of the secondary device do not need to be reset.
