Abstract:
A package includes a first die and a second die. The dies are connected to each other through an interface. The package includes interrupt processing for detecting interrupt information and providing a packet in response to the interrupt information detection. The packet includes an address to which data in the packet is to be written. The interface is configured to transport the packet between the dies. A data store is provided to which the data is writable. An interrupt event is determined from data received in several packets.
Abstract:
An image sensor may include a shared memory resource, which can be selectively used by a digital filter for image scaling or by a defect correction circuit.
Abstract:
A memory management device including a plurality of outputs, each output configured to interface to respective one of a plurality of memories; and a controller configured to cause each buffer allocated to the memories to be divided up substantially equally between each of the plurality of memories.
Abstract:
A first cache arrangement including an input configured to receive a memory request from a second cache arrangement; a first cache memory for storing data; an output configured to provide a response to the memory request for the second cache arrangement; and a first cache controller; the first cache controller configured such that for the response to the memory request output by the output, the cache memory includes no allocation for data associated with the memory request.
Abstract:
A package includes a first die and a second die, at least one of said first and second dies being a memory. The dies are connected to each other through an interface. The interface is configured to transport both control signals and memory transactions. A multiplexer is provided to multiplex the control signals and memory transactions onto the interface such that a plurality of connections of said interface are shared by the control signals and the memory transactions.
Abstract:
An FFT/IFFT processor having computation logic capable of processing butterfly operations, and storage for storing the operands of butterfly operations, including a mechanism for storing the operands of multiple consecutive butterfly operations in contiguous storage locations and wherein the computation logic is capable of simultaneously accessing and processing said multiple butterfly operations.
Abstract:
An arrangement of arithmetic logic units carries out an operation on at least one operand, wherein the operation is determined by operation codes received by the arithmetic logic units. The operation codes and at least one operand are received on a first clock cycle. The result of the operation is output from at least one arithmetic logic unit to at least one further arithmetic logic unit. A result of the plurality of arithmetic logic units is then output on a next clock cycle.
Abstract:
A memory access system including a memory in which data is organized in pages, each page holding a sequence of data elements; means for receiving a requested address including a requested page address and a requested data element address; logic for accessing a current page from the memory using a current page address; logic for reading out data elements of the current page in the sequence in which they are held in memory; logic for comparing the requested page address with the current page address and for issuing a memory access request with the requested page address when they are not the same; and logic operable when the requested page address is the same as the current page address for comparing a requested data element address with the current address of a data element being read out and returning the data element when the requested data element address matches the current data element address.
Abstract:
A semiconductor packaging unit mounts onto a board by solder joints. The unit includes, disposed along one axis, a semiconductor component having on a rear face protruding electrical connection lugs designed to be soldered onto the board and an external cage surrounding the component and having a rear edge designed to be soldered onto the board and a front part through which a front part of the component passes. The component and the cage are designed to axially slide with respect to one another in such a manner as to be brought into their soldering position with respect to the board and having complementary holding parts coming into contact and designed to hold them with respect to one another when they are axially removed from the soldering position and to free them with respect to one another when they are at the soldering position.
Abstract:
An apparatus may include a delay line having a first delay value corresponding to first operating conditions of the apparatus and a second delay value corresponding to second operating conditions of the apparatus. A monitoring circuit may monitor a time taken for a first clock edge of a clock signal to propagate through the delay line. A determining circuit may determine whether operating conditions of the apparatus are acceptable in response to the time taken.
