摘要： A wide data width processor has an execution unit including an aligner that aligns data for load/store instructions and shifts or rotates data for arithmetic logic instructions. Use of the same circuitry and execution unit for these different types of instructions reduces overall circuit size because alignment circuitry need not be repeated, once in a load/store unit and once in an arithmetic logic unit.

摘要： A vector processor provides a data path divided into smaller slices of data, with each slice processed in parallel with the other slices. Furthermore, an execution unit provides smaller arithmetic and functional units chained together to execute more complex microprocessor instructions requiring multiple cycles by sharing single-cycle operations, thereby reducing both costs and size of the microprocessor. One embodiment handles 288-bit data widths using 36-bit data path slices. Another embodiment executes integer multiply and multiply-and-accumulate and floating point add/subtract and multiply operations using single-cycle arithmetic logic units. Other embodiments support 8-bit, 9-bit, 16-bit, and 32-bit integer data types and 32-bit floating data types.

摘要： An instruction decoder in a processor decodes an instruction by creating a decode buffer entry that includes global fields, operand fields, and a set of micro-instructions. Each micro-instruction represent an operation that an associated execution unit can execute in a single clock cycle. A scheduler issues the micro-instructions from one or more entries to the execution units for possible parallel and out-of-order execution. Each execution unit completes an operation, typically, in one clock cycle and does not monitor instructions that may block a pipeline. The execution units do not need separate decoding for multiple stages. One global field indicates which micro-instructions are execute first. Further, micro-instructions have fields that indicate an execution sequence. The scheduler issues operations in the order indicated by the global fields and the micro-instructions. When the last operation for an instruction is completed, the instruction is retired and removed from the decode buffer.

摘要： An instruction fetch unit includes a program buffer for sequential instructions being decoded and a target buffer for an instruction sequence including the target of the next branch instruction. Scan logic coupled to the program buffer scans the program buffer for branch instructions. A target for the first branch instruction is determined and a request to external memory fills the target buffer with a sequence of instructions including a target instruction before sequential decoding reaches the branch instruction. If the branch is subsequently taken, the instructions from the branch target buffer are transferred to the program buffer. The program buffer may be divided into a main and a secondary buffer that have the same size as the target buffer, and an instruction bus between the instruction fetch unit and external memory is sufficiently wide to fill the main, secondary, or target buffer in a single write operation.

摘要： Video data compression techniques reduce necessary storage size and communication channel bandwidth while maintaining acceptable fidelity. Vector quantization provides better overall data compression performance by coding vectors instead of scalars. The search algorithm and VLSI architecture for implementing it is herein disclosed, and such a search algorithm is useful for real-time image processing. The architecture employs a single processing element and external memory for storing the N constant value hyperplanes used in the search, where N is the number of codevectors. The design does not perform any multiplication operation using the constant value hyperplane tree search, since the tree search method is independent of any L.sub.q metric for q between one and infinity. Memory used by the design is significantly less than memory employed in existing architecture.

摘要： The relationship between a sum of applied address operands and a matching virtual page number is exploited to minimize the adder size required for fast number comparison. In one embodiment, variably-sized addresses are accommodated by augmenting a portion of the applied address operands to ensure easy access to potential carry bits. A comparator is used for each virtual page number stored in a translation look-aside buffer to quickly determine whether that virtual page number matches the applied address operand sum.

摘要： An integrated multiprocessor architecture simplifies synchronization of multiple processing units. The multiple processing units constitute a general-purpose or control processor and a vector processor which has a single-instruction-multiple-data (SIMD) architecture so that multiple parallel processing units in the vector processor all complete an instruction simultaneously and do not require software synchronization. The control control processor controls the vector processor and creates a fork in a program flow by starting the vector processor. An instruction set for the control processor includes special instructions that enable the control processor to access registers of the vector processor, start or halt execution by the vector processor, and test flags written by the vector processor to indicate completion of tasks. The two processors then execute separate program threads in parallel until the control processor stops the vector processor, an exception is encountered, or the vector processor completes its program thread and enters an idle state. An instruction set for the vector processor includes special instructions that interrupt the first processor to indicate a task is complete. A register coupled to and accessible by both processors stores a state bit indicating whether the vector processor is running or idle. The control processor can synchronize the separate program threads by executing a loop which polls the state bit. When the state bit indicates the vector processor is idle, the general-purpose processor can process results from the vector processor and restart the vector processor.
