Abstract: A method for arbitrating access to a resource shared by several electronic elements. Each element is allocated a first counting value and a first penalty, the first counting value is decremented in synchronization with a clock signal, and is incremented by a value equal to the first penalty every time the element is selected for an access cycle. When several elements are simultaneously waiting to access the shared resource, an element is selected to access the resource if its first counting value is lower than or equal to a determined threshold, and is lower than the first counting values of the other elements having sent an access request.

Abstract: A dedicated processing module includes an input for data to be processed and an output for processed data. A block input and a block output are also included. A processing component for the module performs a digital processing operation on the data present at the data input and applies the processed data at the data output. The processor may further generate a block request. A control device within the module reproduces, at the block output, a block request applied to the block input or generated by the processing component. The control device thus may operate to block the application of processed data at the data output upon receipt of a block request at the block input. Two or more dedicated processing modules may be connected in series with each other to form a processing flow chain with the data output of one module connected to the data input of a subsequent module. Additionally, the block output of the subsequent module is connected to the block input of the preceding module.

Abstract: Disclosed is a current mirror which maintains good performance when the current to be tracked corresponds to a voltage close to the low supply voltage. This current mirror includes a feedback circuit which causes the first transistor of the reference branch of the mirror to track the voltage of the second transistor of the output branch of the mirror.
