Problems solved by technology

This prior art proposal can be seen as a huge FPGA, since the details of the low-level hardware are very clear, making the compiler orchestration (orchestration) very easy
However, no OS microkernel runs on these blocks

Embodiment Construction

[0016] As shown in Figure 1, multiple processors are distributed on a single-chip structure. Associated with each microprocessor is local data memory, bus interface, and data and instruction caches. Each processor has a core-based operating system. In addition, off-chip components include a memory controller and external RAM.

[0017] The present invention relates broadly to the chip architecture, hardware and software mechanisms that provide a microkernel-based "operating system" for multiprocessor devices. The term operating system in this invention refers to a simple hardware abstraction layer with facilities for supporting thread construction, communication and hardware interface.

[0018] The architecture strives to enable a more general hardware and software solution, higher in performance than ordinary architectures, and general enough to be applicable to various types of software applications and rapid application development. The software system appears to be a sin...

Abstract

A single chip architecture with multiple programmable processors is described. Each processor has a small and fast acting kernel-based operating system which has primitives for performing only fundamental functions of multi-processing. Many distributed threads may be executed simultaneously on many processors while allowing the device to be programmed as a single monolithic system.

Description

technical field [0001] The present invention relates to multiple distributed processors in a single chip array, and more particularly to a small, kernel-based operating system for parallel processing of basic functions performed in multiple processors. Background technique [0002] Embedded systems include special purpose computing systems, typically fully encapsulated by the devices they control. Embedded systems and devices are becoming more popular and used in increasing numbers in both office and home environments. Examples of embedded systems range from portable music players to real-time control of systems like communication networks. As embedded systems become smarter, multiprocessor, distributed architectures are becoming the dominant, not the minority. [0003] The invention provides a single-chip structure with multiple CPU cores, the multiple CPU cores are programmable instruction set processors, and each processor is in a microkernel (or exokernel) distributed ...
