SUMMARY OF THE INVENTION

[0010] In one aspect, the present invention provides a new architecture for computers, computing devices and computer networks. In another aspect, the present invention provides a new programming model for these computers, computing devices and computer networks.

[0011] In accordance with the present invention, all members of a computer network, i.e., all computers and computing devices of the network, are constructed from a common computing module. This common computing module has a consistent structure and preferably employs the same ISA. The members of the network can be, e.g., clients, servers, PCs, mobile computers, game machines, PDAs, set top boxes, appliances, digital televisions and other devices using computer processors. The consistent modular structure enables efficient, high speed processing of applications and data by the network's members and the rapid transmission of applications and data over the network. This structure also simplifies the building of members of the network of various sizes and processing power and the preparation of applications for processing by these members.

[0012] In another aspect, the present invention provides a new programming model for transmitting data and applications over a network and for processing data and applications among the network's members. This programming model employs a software cell transmitted over the network for processing by any of the network's members. Each software cell has the same structure and can contain both applications and data. As a result of the high speed processing and transmission speed provided by the modular computer architecture, these cells can be rapidly processed. The code for the applications preferably is based upon the same common instruction set and ISA. Each software cell preferably contains a global identification (global ID) and information describing the amount of computing resources required for the cell's processing. Since all computing resources have the same basic structure and employ the same ISA, the particular resource performing this processing can be located anywhere on the network and dynamically assigned.

[0013] The basic processing module is a processor element (PE). A PE preferably comprises a processing unit (PU), a direct memory access controller (DMAC) and a plurality of attached processing units (APUs). In a preferred embodiment, a PE comprises eight APUs. The PU and the APUs interact with a shared dynamic random access memory (DRAM) preferably having a cross-bar architecture. The PU schedules and orchestrates the processing of data and applications by the APUs. The APUs perform this processing in a parallel and independent manner. The DMAC controls accesses by the PU and the APUs to the data and applications stored in the shared DRAM.

[0014] In accordance with this modular structure, the number of PEs employed by a member of the network is based upon the processing power required by that member. For example, a server may employ four PEs, a workstation may employ two PEs and a PDA may employ one PE. The number of APUs of a PE assigned to processing a particular software cell depends upon the complexity and magnitude of the programs and data within the cell.

[0015] In a preferred embodiment, a plurality of PEs are associated with a shared DRAM. The DRAM preferably is segregated into a plurality of sections, and each of these sections is segregated into a plurality of memory banks. In a particularly preferred embodiment, the DRAM comprises sixty-four memory banks, and each bank has one megabyte of storage capacity. Each section of the DRAM preferably is controlled by a bank controller, and each DMAC of a PE preferably accesses each bank controller. The DMAC of each PE in this embodiment, therefore, can access any portion of the shared DRAM.

[0016] In another aspect, the present invention provides a synchronized system and method for an APU's reading of data from, and the writing of data to, the shared DRAM. This system avoids conflicts among the multiple APUs and multiple PEs sharing the DRAM. In accordance with this system and method, an area of the DRAM is designated for storing a plurality of full-empty bits. Each of these full-empty bits corresponds to a designated area of the DRAM. The synchronized system is integrated into the hardware of the DRAM and, therefore, avoids the computational overhead of a data synchronization scheme implemented in software.

[0017] The present invention also implements sandboxes within the DRAM to provide security against the corruption of data for a program being processed by one APU from data for a program being processed by another APU. Each sandbox defines an area of the shared DRAM beyond which a particular APU, or set of APUs, cannot read or write data.

[0018] In another aspect, the present invention provides a system and method for the PUs' issuance of commands to the APUs to initiate the APUs' processing of applications and data. These commands, called APU remote procedure calls (ARPCs), enable the PUs to orchestrate and coordinate the APUs' parallel processing of applications and data without the APUs performing the role of co-processors.

[0019] In another aspect, the present invention provides a system and method for establishing a dedicated pipeline structure for the processing of streaming data. In accordance with this system and method, a coordinated group of APUS, and a coordinated group of memory sandboxes associated with these APUs, are established by a PU for the processing of these data. The pipeline's dedicated APUs and memory sandboxes remain dedicated to the pipeline during periods that the processing of data does not occur. In other words, the dedicated APUs and their associated sandboxes are placed in a reserved state during these periods.

[0020] In another aspect, the present invention provides an absolute timer for the processing of tasks. This absolute timer is independent of the frequency of the clocks employed by the APUs for the processing of applications and data. Applications are written based upon the time period for tasks defined by the absolute timer. If the frequency of the clocks employed by the APUs increases because of, e.g., enhancements to the APUs, the time period for a given task as defined by the absolute timer remains the same. This scheme enables the implementation of enhanced processing times by newer versions of the APUs without disabling these newer APUs from processing older applications written for the slower processing times of older APUs.

[0021] The present invention also provides an alternative scheme to permit newer APUs having faster processing speeds to process older applications written for the slower processing speeds of older APUs. In this alternative scheme, the particular instructions or microcode employed by the APUs in processing these older applications are analyzed during processing for problems in the coordination of the APUs' parallel processing created by the enhanced speeds. "No operation" ("NOOP") instructions are inserted into the instructions executed by some of these APUs to maintain the sequential completion of processing by the APUs expected by the program. By inserting these NOOPs into these instructions, the correct timing for the APUs' execution of all instructions are maintained.

[0022] In another aspect, the present invention provides a chip package containing an integrated circuit into which is integrated an optical wave guide.

Fucking awesome!!
