摘要： Hardware and software techniques for interrupt detection and response in a scalable pipelined array processor environment are described. Utilizing these techniques, a sequential program execution model with interrupts can be maintained in a highly parallel scalable pipelined array processing containing multiple processing elements and distributed memories and register files. When an interrupt occurs, interface signals are provided to all PEs to support independent interrupt operations in each PE dependent upon the local PE instruction sequence prior to the interrupt. Processing/element exception interrupts are supported and low latency interrupt processing is also provided for embedded systems where real time signal processing is required. Further, a hierarchical interrupt structure is used allowing a generalized debug approach using debut interrupts and a dynamic debut monitor mechanism.

摘要： A processor with a generalized eventpoint architecture, which is scalable for use in a very long instruction word (VLIW) array processor, such as the manifold array (ManArray) processor is described. In one aspect, generalized processor event (p-event) detection facilities are provided by use of compares to check if an instruction address, a data memory address, an instruction, a data value, arithmetic-condition flags, or other processor change of state eventpoint has occurred. In another aspect, generalized processor action (p-action) facilities are provided to cause a change in the program flow by loading the program counter with a new instruction address, generate an interrupt, signal a semaphore, log or count the p-event, time stamp the event, initiate a background operation, or to cause other p-actions to occur. The generalized facilities are defined in the eventpoint architecture as consisting of a control register and three eventpoint parameters, namely at least one register to compare against, a register containing a second compare register, a vector address, or parameter to be passed, and a count or mask register. Based upon this generalized eventpoint architecture, new capabilities are enabled. For example, auto-looping with capabilities to branch out of a nested auto-loop upon detection of a specified condition, background DMA facilities, the ability to link a chain of p-events together for debug purposes, and others are all important capabilities which are readily obtained.

摘要： An array processor includes processing elements (00, 01, 02, 03, 10, 11, 12, 13, 20, 21, 23, 30, 31, 32, 33) arranged in clusters (e.g., 44, 46, 48, 50) to form a rectangular array (40). Inter-cluster communication paths (88) are mutually exclusive. Due to the mutual exclusivity of the data paths, communications between the processing elements of each cluster may be combined in a single inter-cluster path, thus eliminating half the wiring required for the path. The length of the longest communication path is not directly determined by the overall dimension of the array, as in conventional torus arrays. Rather, the longest communications path is limited by the inter-cluster spacing. Transpose elements of an N×N torts may be combined in clusters and communicate with one another through intra-cluster communications paths. Transpose operation latency is eliminated in this approach. Each PE may have a single transmit port (35) and a single receive port (37). Thus, the individual PEs are decoupled from the array topology.

摘要： A computing architecture and software techniques are described which modifies the basic sequential instruction fetching mechanism of a processor by separating a program's control flow from its functional execution flow. A compiled sequential HLL program's static control structures are analyzed and a separate program based on its own unique instructions is created that primarily generates addresses for the selection of functional execution instructions. The original program is now represented by an instruction fetch program and a set of function/logic execution instructions. This basic split allows multiple instruction addresses to be generated in parallel to access multiple instruction memories. These multiple instruction memories contain only the function/logic instructions of the program and no control structure operations such as branches or calls. All the original program's control instructions are split from the original program and used to create the instruction addressing program. This approach allows a variable number of instructions to be issued in parallel whenever the program can allow for it. The instructions of this approach are referred to herein as assembled variable length instructions or AVLIs. Alternative techniques are provided that deal with conditional and unconditional branches. In addition, all or a majority of duplicate function/logic instructions can be removed relying on a single copy or a small number of copies to be stored and referenced as needed by the control program based on architecture features so that overall instruction storage can be reduced.

摘要： Efficient computation of complex long multiplication results and an efficient calculation of a covariance matrix are described. A parallel array VLIW digital signal processor is employed along with specialized complex long multiplication instructions and communication operations between the processing elements which are overlapped with computation to provide very high performance operation. Successive iterations of a loop of tightly packed VLIWs may be used allowing the complex multiplication pipeline hardware to be efficiently used.
