Abstract: This invention is data processing apparatus and method. Data is protecting from corruption using an error correction code by generating an error correction code corresponding to the data. In this invention the data and the corresponding error correction code are carried forward to another set of registers without regenerating the error correction code or using the error correction code for error detection or correction. Only later are error correction detection and correction actions taken. The differing data/error correction code registers may be in differing pipeline phases in the data processing apparatus. This invention forwards the error correction code with the data through the entire datapath that carries the data. This invention provides error protection to the whole datapath without requiring extensive hardware or additional time.

Abstract: A method to eliminate the delay of a block invalidate operation in a multi CPU environment by overlapping the block invalidate operation with normal CPU accesses, thus making the delay transparent. A range check is performed on each CPU access while a block invalidate operation is in progress, and an access that maps to within the address range of the block invalidate operation will be treated as a cache miss to ensure that the requesting CPU will receive valid data.

Abstract translation: 通过将块无效操作与正常CPU访问重叠来消除多CPU环境中的块无效操作的延迟的方法，从而使得延迟变得透明。 在块无效操作正在进行时，对每个CPU访问执行范围检查，并且映射到块无效操作的地址范围内的访问将被视为缓存未命中，以确保请求的CPU将接收有效数据 。

Abstract: A method includes determining, by a level one (L1) controller, to change a size of a L1 main cache; servicing, by the L1 controller, pending read requests and pending write requests from a central processing unit (CPU) core; stalling, by the L1 controller, new read requests and new write requests from the CPU core; writing back and invalidating, by the L1 controller, the L1 main cache. The method also includes receiving, by a level two (L2) controller, an indication that the L1 main cache has been invalidated and, in response, flushing a pipeline of the L2 controller; in response to the pipeline being flushed, stalling, by the L2 controller, requests received from any master; reinitializing, by the L2 controller, a shadow L1 main cache. Reinitializing includes clearing previous contents of the shadow L1 main cache and changing the size of the shadow L1 main cache.

Abstract: An apparatus includes first CPU and second CPU cores, a L1 cache subsystem coupled to the first CPU core and comprising a L1 controller, and a L2 cache subsystem coupled to the L1 cache subsystem and to the second CPU core. The L2 cache subsystem includes a L2 memory and a L2 controller configured to operate in an aliased mode in response to a value in a memory map control register being asserted. In the aliased mode, the L2 controller receives a first request from the first CPU core directed to a virtual address in the L2 memory, receives a second request from the second CPU core directed to the virtual address in the L2 memory, directs the first request to a physical address A in the L2 memory, and directs the second request to a physical address B in the L2 memory.
