In one example, a memory controller includes one or more registers that include pointers to free lists that include addresses of free locations in the memory devices. In various example, each free list corresponds to a memory device, memory module, or pseudo channel. The memory controller receives data to store in memory.

In one example, at least one of the memory devices is selected to store data chunks based on how recently the memory device was selected.

A timer correction value is calculated based on the differences between the first primary and secondary timer values and the second primary and secondary timer values. The timer correction value is applied to the secondary timer circuitry to synchronize the primary timer circuitry with the secondary timer circuitry.

A new approach is proposed to support hardware-based update of a software (e.g., a firmware) of an electronic device in a non-functional state. Under the proposed approach, the software is stored securely on a resource (e.g., a non-volatile storge) protected by a hardware-based lock mechanism. A first agent acquires a lock and authenticate the software. When a boot failure (e.g. authentication of the software fails) of the electronic device happens, an alert indicating the failure is generated and sent to a second agent (e.g., a sideband master) through an alert mechanism. The second agent then acquires a lock from the hardware-based lock mechanism to obtain exclusive excess to the resource and update the software stored in the non-volatile storage through, e.g., block write and/or read operations. The second agent then verifies that the software has been updated successfully so that the electronic device becomes functionally again.

The present disclosure describes apparatuses and methods for hybrid logical to physical (LTP) address mapping in memory systems. In various aspects, a memory controller maps, with an interleave map mode, a first portion of logical address space to a first portion of the physical address space of a memory. The memory controller also maps, with a fixed map mode, a second portion of logical address space to a second portion of the physical address space of the memory. Thus, the memory controller may configure some memory banks with interleave address mapping and other banks with fixed address mapping. In some cases, the memory controller may reconfigure a bank of the memory from one mapping mode to the other mapping mode. By so doing, the memory controller can leverage benefits provided by either mapping mode to optimize access performance, reduce power consumption, or isolate defective areas with minimal capacity loss.

METHOD OF USING UNIT VECTORS TO ALLOW EXPANSION AND COLLAPSE OF HEADER LAYERS WITHIN PACKETS FOR ENABLING FLEXIBLE MODIFICATIONS AND AN APPARATUS THEREOF
Embodiments of the apparatus for modifying packet headers relate to a use of bit vectors to allow expansion and collapse of protocol headers within packets for enabling flexible modification. A rewrite engine expands each protocol header into a generic format and applies various commands to modify the generalized protocol header. The rewrite engine maintains a bit vector for the generalized protocol header with each bit in the bit vector representing a byte of the generalized protocol header. A bit marked as 0 in the bit vector corresponds to an invalid byte, while a bit marked as 1 in the bit vector corresponds to a valid byte. The rewrite engine uses the bit vector to remove all the invalid bytes after all commands have been operated on the generalized protocol header to thereby form a new protocol header.

Systems and methods for using a physical layer transceiver (PHY) of an automobile to avoid data signal collision on a high noise or interference automotive multi-drop communication link are provided. A signal is received at a first PHY via a multi-drop communication link in a high noise or interference automotive environment. The received signal is separated into a first spectral component corresponding to a first logic level and into a second spectral component corresponding to a second logic level. Based on analysis of the first and second spectral components, respectively, a determination is made as to whether a second PHY device is concurrently transmitting data on the link, by determining whether both the first and second logic levels are detected in the first and second spectral components within a threshold period of time of one another. The first PHY device is permitted to transmit, or prevented from transmitting, data via the link based on whether the second PHY device is transmitting data on the link.
Embodiments of the present invention relate to multiple parallel lookups using a pool of shared memories by proper configuration of interconnection networks.

Each lookup is allocated a set of tiles based on the memory capacity needed by that lookup. The tiles allocated for each lookup do not overlap with other lookups such that all lookups can be performed in parallel without collision. Each lookup is reconfigurable to be either hash-based or direct-access. The interconnection networks are programed based on how the tiles are allocated for each lookup.
