    摘要: A random number generator comprises random number generation circuitry to generate and output random bits. The random number generator includes interface circuitry to receive and store random bits output by the random number generation circuitry and to output random bits. The interface circuitry prevents outputting the same random bits more than once.

    摘要: A circuit for selecting a select line from a plurality of first and second select lines is described. Each of an array of integrated circuit (IC) packages is coupled to (1) one of the first select lines and (2) at least one of the second select lines. The circuit includes a decoder for decoding a select data to select the select line, and circuitry for modifying the select data before the select data is applied to the decoder when each of the second select lines is not coupled to an IC device within each of the IC packages to ensure that the select line is not one of the second select lines. When each of the first and second select lines is coupled to an IC device within each of the IC packages, the circuitry for modifying does not modify the select data. A method for selecting a selected IC device within a selected IC package of an array of IC packages is also described.

    摘要: A method for managing and addressing an executable-in-place (XIP) program stored in a memory having a plurality of blocks includes the step of virtually storing a first portion of the XIP program in a first page of a paged virtual memory space and a second portion of the XIP program in a second page of the paged virtual memory space. The first portion of the XIP program is physically stored in a first block of the plurality of blocks and the second portion of the XIP program is physically stored in a second block of the plurality of blocks. A memory address mapping window is established with addresses of the first block. A page map for mapping the memory address mapping window to the first page is established. The first block is addressed for the first portion of the XIP program via the page map and the memory address mapping window. The memory address mapping window is updated with addresses of the second block and the page map is remapped to the second page when the second portion of the XIP program requires to be accessed such that the XIP program can be directly executed from the memory without being required to be stored contiguously in the memory and without being partitioned from other files that are not XIP programs.
