Design and implementation of an embedded multiprocessor system, SAM-II
Rodoslav Dervishev · Summit (Simon Fraser University) · 1995
The Structured Architecture Machine (SAM-11) board-level hardware and system software design and implementation concepts are discussed.SAM-II is An Embedded Multiprocessor Vector-Oriented Computer System based on a custom 32 bit RISC chip set designed at the VLSI and Computer Design Laboratory and intended for low-cost array processing and computationally intensive applications.The prototype is designed to accommodate up to five processing units connected to a DS80C320 microcontroller based mother-board bus.FPGA based logic is designed to implement bus control and processing units control interface functions and also to realize selection, deselection and broadcasting interfacing capabilities, allowing efficient access to the multiprocessor environment within a single DS80C320 machine cycle.The use of the SJCP custom datafcontrol interface incorporating interfacing and boundary-scan testing capabilities is also discussed in the context of system hardware concepts, testing, and processing unit resource access. 3.4.
