A data-processing system and method are disclosed, which include a cached processor for processing data, and a plurality of memory components that communicate with the cached processor. The cached processor is separated from the memory components such that the cached processor provides support for the memory components, thereby providing a diffused memory architecture with diffused memory capabilities. The memory components can constitute, for example, memory devices such as diffused memory, matrix memory, R-Cell memory components, and the like, depending on design considerations.

All purpose processor implementation to support different types of cache memory architectures

A data-processing system and method include a processor core associated with a cache controller. A plurality of cached memory components is associated with the processor core and the cache controller. A cached processor is provided, which supports a plurality of varying sizes of instruction and data cache, wherein the cached processor comprises a processor core separated from the cache controller and the plurality of cached memory components, thereby permitted the cached processor to support varying sizes of cache memory in a flexible memory arrangement thereof.

Data-processing system and method for supporting varying sizes of cache memory

A method and apparatus are provided for interfacing between a data source and a tightly-coupled memory. In the method and apparatus, a write data word and a write address are received from the data source and latched in a first clock cycle within a write buffer along a write data path, between the data source and the memory. The write data word is encoded according to an error detection code along the write data path. The write address and the write data word are applied to the memory from the write buffer. The write data word is accessible to the data source from the write data path or the memory beginning with a second clock cycle, which is a next subsequent clock cycle to the first clock cycle.
