Image processing on the massively parallel processor
TLDR
The massively parallel processor's computing power and extreme flexibility will allow the development of new techniques for scene analysis - realtime scene analysis, for example, in which the sensor can interact with the scene as needed.Abstract:
A review of the massively parallel processor (MPP) is provided. The MPP, a single instruction, multiple data parallel computer with 16K processors being built for NASA by Goodyear Aerospace, can perform over six billion eight-bit adds and 1.8 billion eight-bit multiplies per second. Its SIMD architecture and immense computing power promise to make the MPP an extremely useful and exciting new tool for all types of pattern recognition and image processing applications. The SIMD parallelism can be used to directly calculate 16K statistical pattern recognition results simultaneously. Moreover, the 16K processors can be configured into a two-dimensional array to efficiently extract features from a 128x128 subimage in parallel. The parallel search capability of SIMD architectures can be used to search recognition and production rules in parallel, thus eliminating the need to sort them. This feature is particularly important if the rules are dynamically changing. Finally, the MPP's computing power and extreme flexibility will allow the development of new techniques for scene analysis - realtime scene analysis, for example, in which the sensor can interact with the scene as needed.read more

ComputeDRAM: In-Memory Compute Using Off-the-Shelf DRAMs
TL;DR: This work is the first work to demonstrate in-memory computation with off-the-shelf, unmodified, commercial, DRAM, by violating the nominal timing specification and activating multiple rows in rapid succession, which happens to leave multiple rows open simultaneously, thereby enabling bit-line charge sharing.

Validity of the single processor approach to achieving large scale computing capabilities
TL;DR: In this paper, the authors argue that the organization of a single computer has reached its limits and that truly significant advances can be made only by interconnection of a multiplicity of computers in such a manner as to permit cooperative solution.
