Patent ID: 7389373

Claim:
Arbitration device, designed to be connected between, on the one hand, a first and a second module and, on the other hand, storing means forming a memory workspace, the device comprising: means of detecting one or more requests coming, concurrently or not, from the first and second modules, for the purpose of accessing the memory workspace; selection means generating a selection signal assuming: a first state, by default or if a single detected request comes from the first module or else if two requests are detected concurrently; and a second state, if a single detected request comes from the second module or if one of two concurrently detected requests has already been served; first clock means, activated if the selection signal assumes the first state, and generating a first clock signal enabling the storing means to serve a request coming from the first module; first reset means, activated if the selection signal assumes the first state, and generating a first reset signal making it possible to erase a request coming from the first module after it has been served; second clock means, activated if the selection signal assumes the second state, and generating a second clock signal enabling the storing means to serve a request coming from the second module; and second reset means, activated if the selection signal assumes the second state, and generating a second reset signal, making it possible to erase a request coming from the second module after it has been served.
