Abstract
Access to data storage is described. A general-purpose processor and an auxiliary processing unit (APU) interface coupled to the general-purpose processor are provided. Data storage coupled to the general-purpose processor via the APU interface is provided for a fixed or low variable read latency access and a fixed write latency access to the data storage. A first instruction is passed to the general-purpose processor and to the APU interface. The first instruction is identified as part of a set of instructions accessible by the APU interface. The first instruction is used to write data into the data storage. A second instruction is passed to the general-purpose processor and to the APU interface. The second instruction is identified as part of the set of instructions accessible by the APU interface. The second instruction is used to read the data from the data storage, and the data is then output.
