Expeed

The Nikon Expeed image/video processors (often styled EXPEED) are media processors for Nikon's digital cameras.

They perform a large number of tasks:

Expeed's multi-processor system on a chip solution integrates an image processor in multi-core processor architecture, with each single processor-core able to compute many instructions/operations in parallel. Storage and display interfaces and other modules are added and a digital signal processor (DSP) increases the number of simultaneous computations. On-chip 32-bit microcontroller initiates and controls the operation and data transfers of all processors, modules, interfaces and can be seen as the main control unit of the camera.

In each generation Nikon uses different versions for its professional and consumer DSLRs / MILCs, whereas its compact cameras use completely different architectures. This is different from for example Canons DIGIC: its professional DSLRs double the processors of its consumer DSLR series. The Expeed is an application-specific integrated circuit (ASIC) built by Socionext specifically for Nikon designs according to Nikon specifications.
