Problems solved by technology

[0006] System-on-a-chip (SOC) devices increase the complexity of the system, so SOC systems are difficult to design and expensive to change
Changes and designs can be made easier by adding a configurable logic array to the processor core connected to the processor core, so the logic in the configurable logic array can be configured using industrial tools combined with the use of programmable logic , while processor cores can be programmed using known software programming techniques, but the problem of configuration data management for configurable logic array modules still exists
The typical problem encountered by SoC technology in complex systems is that it is difficult to design and expensive to change. Combining the configurable logic array with the processor core, the combination of logic can be changed with the improvement of the processor, that is, Logic configuration can be achieved through the programmable logic array configuration tool

Abstract

A system-on-a-chip integrated circuit that includes a configurable logic array, a processor core, and a memory adapted to store instructions for a mission function, and instructions for a configuration load function used to load configuration data on to the integrated circuit via an input port on the integrated circuit from an external source. The processor fetches and executes the instructions from the memory. Configuration data received using the configuration load function is used to configure the configurable logic array. The present invention provided a higher degree of freedom for system-on-chip design using a built-in logic array that can be set, and to provide a setting load of a logic that can be set.

Description

technical field [0001] The present invention relates to a system-on-chip integrated circuit and other processor devices including an embedded configurable logic array as application-specific or custom chip logic. technical background [0002] Configurable logic arrays known as programmable logic devices (PLDs) and field programmable gate arrays (FPGAs), and more widely known as programmable logic arrays (PLAs), have increasingly higher density Design, technology for configuring such high-density devices often requires specific logic to be executed on-chip or on a host processor that communicates with the configurable logic array via the system bus. Configuration data management of the Configurable Logic Array core requires complex logic, see US Patent No. 6,049,222 to Lawman, the particular technique used to configure the device limits the environments in which it can be applied. [0003] The configurable logic array can load a configuration data by the user to set the spec...
