摘要： A data processing apparatus which uses a register file to provide a faster alternative to indirect memory addressing. A functional unit is connected to a data register file (76) which comprises a plurality of registers, each of which is accessed by a corresponding register number. The functional unit (e.g., A-unit 78) can execute at least one indirect register access instruction that comprises an operand register number field. Instruction decode circuitry, connected to the register file and the functional unit, is responsive to the indirect register access instruction to recall data stored in an operand register (190) specified by the operand register number in the instruction, identify the recalled data as a register access number, and recall operand data from a data register corresponding to the register access number for use as an operand by the functional unit. Indirect register addressing permits the apparatus to more quickly execute table look up intensive algorithms, such as variable length decoding, than an apparatus employing only indirect memory addressing.

摘要： An embodiment of the invention includes a pair of parallel 16×16 multipliers each with two 32-bit inputs and one 32-bit output. There are options to allow input halfword and byte selection for four independent 8×8 or two independent 16×16 multiplications, real and imaginary parts of comple×multiplication, pairs of partial sums for 32×32 multiplication, and partial sums for 16×32 multiplication. There are options to allow internal hardwired routing of each multiplier unit results to achieve partial-sum shifting as required to support above options. There is a redundant digit arithmetic adder before final outputs to support additions for partial sum accumulation, complex multiplication vector accumulation and general accumulation for FIRs/IIRs—giving MAC unit functionality. There are options controlled using bit fields in a control register passed to the multiplier unit as an operand. There are also options to generate all of the products needed for complex multiplication.

摘要： A data processing system is provided with a digital signal processor (DSP) which has a shuffle instruction for shuffling a source operand (600) and storing the shuffled result in a selected destination register (610). A shuffled result is formed by interleaving bits from a first source operand portion with bits from a second operand portion. A de-interleave and pack (DEAL) instruction is provided for de-interleaving a source operand. The shuffle instruction and the DEAL instruction have an exactly inverse effect. The DSP includes swizzle circuitry that performs interleaving or de-interleaving in a single execution phase.

摘要： A transfer request bus and transfer request bus node is described which is suitable for use in a data transfer controller processing multiple concurrent transfer requests despite the attendant collisions which result when conflicting transfer requests occur. Transfer requests are passed from an upstream transfer request node to downstream transfer request node and then to a transfer request controller with queue. At each node a local transfer request can also be inserted to be passed on to the transfer controller queue. Collisions at each transfer request node are resolved using a token passing scheme wherein a transfer request node possessing the token allows a local request to be inserted in preference to the upstream request.

摘要： A method for implementing a variable length delay instruction includes the steps of designating a source register for holding information and designating a destination register for retrieving the information. A first number of cycles before retrieval of the information to the destination register then is determined, and the information is transferred from the source register to delaying device, such as queuing device, for the first number of cycles. Finally, the information is written from the delaying device to the destination register. An apparatus for implementing variable length delay instructions includes an input line for reading information from a source register; delaying device for receiving said information read from the source register; a multiplexer; and a select line. A trigger signal is transmitted to the multiplexer, thereby instructing the multiplexer to write the information to a destination register.

摘要： A logging tool having a tool body, which can be positioned in a fluid-filled borehole, including a receiver section and a dipole transmitter; wherein the dipole transmitter includes a transducer with a shell having a reaction mass and a motor located therein, the motor operatively connecting the shell and the reaction mass such that only an outer surface of the shell is in contact with the fluid in the borehole. This new type of dipole source for well logging involves shaking all or part (axially) of a dipole tool body to produce a pure, broadband acoustic dipole signal while at the same time coupling as little energy as possible into the tool body. Important variations on this idea include a linear phased array of shaker sources, and active cancellation of tool borne noise.

摘要： A data processing system is provided with a digital signal processor which has an instruction for conditionally branching based on the contents of a specified test register. Each time a branch is taken, the register is decremented as a side effect of executing the branch instruction. In addition, a predicate register is specified by the instruction. A branch occurs only if both registers meet specified conditions.

摘要： A data processing system having a central processing (CPU) unit and a method of operation is provided. The CPU has an instruction set architecture that is optimized for intensive numeric algorithm processing. The CPU has dual load/store units connected to dual memory target ports of a memory controller. The CPU can execute two aligned data transfers each having a length of one byte, two bytes, four bytes, or eight bytes in parallel by executing two load/store instructions. The CPU can also execute a single non-aligned data transfer having a length of four bytes or eight bytes by executing a non-aligned load/store instruction that utilizes both memory target ports. A data transfer address for each load/store instruction is formed by fetching the instruction, decoding the instruction to determine instruction type, transfer data size, and scaling selection, selectively scaling an offset provided by the instruction and combining the selectively scaled offset with a base address value. The resultant address is then provided to the memory system to initiate a data transfer.
