A multi-chiplet module system, method and device including a memory storing chiplet operational data and a plurality of chiplets serially operably coupled to each other forming a chiplet chain. The chiplets in the middle and at one end of the chain each include a local cache with the chiplet at the one end of the chain coupling with the memory. When one of the chiplets requires data stored on the memory it checks the local cache (if it has one), and if not in the local cache, it then queries the cache of the next chiplet in the chain until the required data is propagated from the memory up the caches of the chain to the requesting chiplet.

Multi-chiplet module system, method and device

A new approach is proposed to support a hardware-based lock mechanism having a hardware-based lock unit associated with a resource, wherein the lock is utilized by an arbitrator to arbitrate between multiple agents requesting access to the resource. When a first agent requests access to resource in unlocked state, the arbitrator creates a lock ID and set a locked state indicating that the resource is locked. The lock ID is provided to the first agent, which now has exclusive control over the resource. The arbitrator ensures that any agent with the same ID may access the resource. When a second agent requests access to the resource with a lock ID to the arbitrator, it is granted access to the resource if the lock ID provided matches the one stored on the lock unit. If there is a mismatch between the lock IDs, access to the resource is denied.

System and methods for firmware security mechanism

A new approach is proposed that contemplates systems and methods to support post reset fuse reload for latency reduction. First, values of fuses are read once and stored into one or more load registers on an electronic device, wherein the load registers are protected. Once the values of the fuse are loaded into the load registers, a valid indicator of the load registers is set indicating that the values have been successfully loaded into the load registers. When other components of the electronic device need to access these values, the other components will check the load registers first. If it is determined that the valid indicator of the load registers is set, the stored values are read from the load registers instead of from the fuses. If the valid indicator of the load registers is not set, the values are loaded again from the fuses into the load registers.
