Abstract
Described is a scalable interface including a plurality of 2-bit transmission channels. An encoder partitions a digital bit stream into 3 bits which are coded into 4 bits with each pair of bits in each 4 bit pattern transmitted via back-to-back clock cycles on separate ones of the channels.
Claims19
A system including:
- n transmission channels, n greater than 1;
- and
- an encoder that codes data to be transmitted on said n transmission channels, said encoder including a first circuit that partitions a bit stream into groups of 3-bit pattern;
- a second circuit that generates a 4-bit pattern for each group of 3-bit pattern;
- and
- a third circuit that distributes, each pair of bits in a 4-bit pattern over different ones of the n transmission channels.
3 more elements
A system including:
- a source device;
- a sink device;
- and
- a first interface interconnecting the source device to the sink device;
- said first interface including
- n transmission channels, n greater than 1;
- and
- an encoder that spreads a pair of bits from each 4-bit pattern to be transmitted over different ones of the n channels.
5 more elements
A method for transmitting data comprising the acts of:
- (a) providing n transmission channels, n>1;
- (b) providing groups of 4-bit pattern to be transported by said channels;
- (c) distributing each of the group of 4-bit pattern in such a way that bits in each pair of 4-bit pattern are placed on separate ones of the n transmission channels.
A system including:
- a source device;
- a sink device;
- an interface interconnecting the source device to the sink device, said interface including n transmission channels, n>1;
- and
- an encoder that spread bits from an m-bit pattern, m>1 over different ones of the transmission channel.
2 more elements
A system comprising:
- n transmission channels, n>1;
- and
- an encoder that distributes selected bits from at least one group of m bits, m>1, over different ones of the n transmission channels.
