摘要： A method and apparatus for performing a memory dump. The method includes providing a memory location from a debugger to a memory array through a BIST wrapper, and receiving data by the debugger read from the memory location in the memory array. The method can include sending a dump enable signal from the debugger, and the BIST wrapper selectively providing the memory location to the memory array in response to the dump enable signal. The method can include sending the dump enable signal to a multiplexer coupled to a register in the BIST wrapper, the dump enable signal causing the multiplexer to load the register with the memory location. The method can include asynchronously sending a write disable signal to the memory array before reading the data from the memory location. The received data can be selected from a larger set of data read from the memory location.

摘要： In a particular embodiment, a method includes receiving a testing activation signal at a controller coupled to a semiconductor device. The method further includes biasing a well of at least one transistor of the semiconductor device in response to the received testing activation signal. The bias is provided by a biasing circuit that is responsive to the controller. While the well is biased, a test of the semiconductor device is performed to generate testing data.

摘要： A feedback scan isolation and bypass architecture apparatus and method. The apparatus includes core logic, and input and output multiplexers. The input multiplexer selectively provides a functional input or the core output to the core input based on a test signal. The output multiplexer selectively provides the core output or the input multiplexer output to a functional output based on the test signal. When the test signal indicates core feedback testing, the output multiplexer outputs the core output and the input multiplexer feeds back the core output to the core input. When the test signal indicates bypass testing, the input multiplexer outputs the functional input and the output multiplexer outputs the functional input bypassing the core logic. Logic can block the feedback or bypass signals when there are timing issues. Logic can modify the number of feedback or bypass signals when the number of functional inputs and outputs are different.

摘要： An apparatus and method to translate virtual addresses to physical addresses in a base plus offset addressing mode are disclosed. In an embodiment, a method includes performing a first translation lookaside buffer (TLB) lookup based on a base address value to retrieve a speculative physical address. While performing the TLB lookup based on the base address value, the base address value is added to an offset value to generate an effective address value. The method also includes performing a comparison of the base address value and the effective address value based on a variable page size to determine whether the speculative physical address corresponds to the effective address.

摘要： A method and apparatus for controlling system access to a memory that includes receiving first and second instructions, and evaluating whether both instructions can architecturally complete. When at least one instruction cannot architecturally complete, delaying both instructions. When both instructions can architecturally complete and at least one is a write instruction, adjusting a write control of the memory to account for an evaluation delay. The evaluation delay can be sufficient to evaluate whether both instructions can architecturally complete. The evaluation delay can be input to the write control and not the read control of the memory. A precharge clock of the memory can be adjusted to account for the evaluation delay. Evaluating whether both instructions can architecturally complete can include determining whether data for each instruction is located in a cache, and whether the instructions are memory access instructions.
