The Cyrix 6x86, the alone x86-compatible desktop processor to absorb a committed Scratchpad.
SuperH, acclimated in Sega's consoles, could lock cachelines to an abode alfresco of capital anamnesis for use as a Scratchpad.
The Sony PS1's R3000 had a Scratchpad instead of an L1 cache. It was accessible to abode the CPU assemblage here, an archetype of the acting workspace usage.
Sony's PS2 Emotion Engine active a 16KiB Scratchpad, to and from which DMA transfers could be issued to its GS, and capital memory.
The Cell's SPEs are belted absolutely to alive in their "local-store", relying on DMA for transfers from/to capital anamnesis and amid bounded stores, abundant like a Scratchpad. In this regard, added account is acquired from the abridgement of accouterments to analysis and amend adherence amid assorted caches: the architecture takes advantage of the acceptance that anniversary processor's workspace is abstracted and private. It is accepted this account will become added apparent as the cardinal of processors scales into the "many-core" future.
Many added processors acquiesce L1 accumulation curve to be locked.
Most DSPs use a Scratchpad. Many accomplished 3D accelerators and bold consoles (including the PS2) accept acclimated DSPs for acme transformations. This differs with the beck based access of avant-garde GPUs which accept added in accepted with a CPU cache's functions.
NVIDIA's 8800 GPU active beneath CUDA provides 16KiB of Scratchpad per thread-bundle back actuality acclimated for gpgpu tasks.
Ageia's PhysX dent utilizes Scratchpad RAM in a address agnate to the Cell; its approach states that a accumulation bureaucracy is of beneath use thancomputer application managed physics and blow calculations. These memories are additionally banked and a about-face manages transfers amid them
