A Moving Threads Processor Architecture MTPA

Martti Forsell, Ville Leppänen, A Moving Threads Processor Architecture MTPA. Journal of Supercomputing 57(1), 5–19, 2011.

Abstract:

Moving threads is a new kind of approach for multicore processor architectures.
Traditionally, each thread stays in the core where it is created, and data is
moved from the main memory via caches to each core and thread. In the moving
threads approach, each core can access only a certain portion of the main memory
via its local memory block, and thus extremely lightweight threads are moved between
the cores. As a consequence, all kinds of cache coherence problems and need
for read reply messages are eliminated. Also Lamport’s sequential consistency of
shared memory multiprocessor systems is achieved for free. In this paper, we propose
a processor architecture (MTPA) for the moving threads paradigm.We describe
the overall structure, operation, instruction set, and thread management mechanism
as well as evaluate the proposed architecture with different functional unit settings
with simulations and give early silicon area and power consumption estimates.
