There are provided methods and computer program products for implementing instruction set architectures with non-contiguous register file specifiers. A method for processing instruction code includes processing a fixed-width instruction of a fixed-width instruction set using a non-contiguous register specifier of a non-contiguous register specification. The fixed-width instruction includes the non-contiguous register specifier.

Apparatus for passively tracking expired data in a dynamic memory includes a time stamp memory configurable for storing information relating to a refresh status of one or more corresponding data entries in the dynamic memory. The apparatus further includes a timer configurable for defining a desired window of time in which a refresh operation of data in the dynamic memory is to occur in order to ensure that the data is valid. Control circuitry is coupled to the time stamp memory and to the timer. The control circuitry is operative to manage the information stored in the time stamp memory relating to the refresh status of the one or more corresponding data entries in the dynamic memory.

An ultra high speed address decoder uses a combination of Domino logic circuits and LSDL logic circuits. N address bits are converted into N logic true address bits and N complementary address bits. A partial address decoder generates two bit groups using selected of the N logic true address bits and N complementary address bits in NOR logic structures such only two cascaded NFETS are used in a logic tree. The bit groups are partitioned to optimize the layout of the parallel bit lines in the address decoder.

A spacer-connector stud comprises a stacked array of glass epoxy laminates, each laminate having a copper layer laminated thereto. The top and bottom laminates of the stud include a spatial array of thermal contacts suitable as a footprint for C4 bump technology. A location is selected on a circuitized base card to accommodate the laminated stud. The stud has a thickness greater than twice the thickness of the components attached to the card. The thermal contacts on the stud, typically solderable, join to a wiring array on the card. A second multi-chip module card having attached and interconnected components on both sides of the second card is mechanically aligned with the based card and pressed against the contacts on the top layer of the stud to form an assembly. The assembly is heated causing the second card to become soldered to the contact footprint on the stud.

A central processing unit system includes: a pipeline configured to receive an instruction; and a register file partitioned into one or more subarrays where (i) the register file includes one or more computation elements and (ii) the one or more computation elements are directly connected to one or more subarrays.

There are provided methods and computer program products for generating code for an architecture encoding an extended register specification. A method for generating code for a fixed-width instruction set includes identifying a non-contiguous register specifier. The method further includes generating a fixed-width instruction word that includes the non-contiguous register specifier.

A method and system for scanning data from a specific latch in a matrix array of latches. The matrix array is made up of vertical selector lines and horizontal data lines. Each latch is coupled at an intersection of a selector line and a data line by a transistor. By turning on the transistor, the contents of the latch can be selectively read or written to.
