Abstract
A method can be used for transmission of at least one packet of at least one bit over a serial link capable of taking two different states respectively associated with the two possible logical values of the at least one transmitted bit. Starting from a transmission start time of the at least one bit and up to the expiration of a first portion of a bit time associated with the at least one bit, the link is placed in one of its states depending on the logical value of the at least one bit. Upon the expiration of the first portion of this bit time, a first additional transition is generated over the link so as to place the link in its other state up to the expiration of the bit time.
Claims20
An electronic device for communicating bits at configurable rates over a serial link, the electronic device comprising a transmission processing unit configured to:
- transmit a first portion of a first bit over the serial link, the first portion having a first bit time;
- transmit a second portion of the first bit over the serial link, the second portion having a second bit time, a logic state of the second portion being different than a logic state of the first portion;
- and
- transmit a second bit over the serial link at a third bit time, the third bit time corresponding to a ratio between the first bit time and a sum of the first bit time and the second bit time.
A method for communicating bits at configurable rates over a serial link, the method comprising:
- transmitting a first portion of a first bit over the serial link, the first portion having a first bit time;
- transmitting a second portion of the first bit over the serial link, the second portion having a second bit time, a logic state of the second portion being different than a logic state of the first portion;
- and
- transmitting a second bit over the serial link at a third bit time, the third bit time corresponding to a ratio between the first bit time and a sum of the first bit time and the second bit time.
