The invention may relate to a method of programming a programmable non-volatile device. The programmable non-volatile device may be programmed while coupled to a circuit in which the programmable non-volatile device is to be used. The method may include establishing a connection and communicating information. The connection may be established from an external device to a test interface of the circuit. The information may be communicated from the external device through the test interface, for programming the programmable non-volatile device.

Programmable device and method of programming

An apparatus comprising a shared memory and a multiprocessor logic circuit. The shared memory may be configured to store data. The multiprocessor logic circuit may comprise a plurality of processors and a message circuit. The message circuit may be configured to pass messages between the processors.

Method for multiprocessor communication within a shared memory architecture

A circuit generally comprising a memory element and a controller. The memory element may define a semaphore allocatable to a resource. The controller may be configured to (i) present a granted status in response to a processor reading a first address while the semaphore has a free status, (ii) set the semaphore to a busy status in response to presenting the granted status, and (iii) present the busy status in response to the processor reading the first address while the semaphore has the busy status.
