Claims
- 1. In a computer system comprising a master device and at least one memory device, a process for transmitting memory requests to the memory device comprising the steps of:
- transmitting a first portion of count information onto a group of bus lines in a word of a packet to the memory device;
- transmitting additional portions of count information onto the group of bus lines in at least one adjacent subsequent word of the packet; and
- receiving the portions of count information from the group of bus lines by a group of receiver means at the memory device, said group of receiver means located in proximity to each other, the number of bus lines utilized to transmit the count information selected to minimize the number of crossings between spatial regions delineated by each of the receiver means;
- wherein the length of wiring between each of the group of the receiver means and therefore the length of wiring needed to process the count information received at the group of receiver means is minimized.
- 2. The process for transmitting memory requests as set forth in claim 1, wherein said group of receiver means comprises receiver buffer means, each receiver buffer means coupled to received information from one of the group of bus lines transmitting portions of count information, the length of wiring being decreased by minimizing the number of wires required to transmit information from one receiver buffer means to another receiver buffer means to process the count information.
- 3. The process for transmitting memory requests as set forth in claim 1, wherein a first portion of count information is transmitted in a third word of the packet and the second portion of count information is transmitted in a fourth word of the packet.
- 4. In a computer system comprising a master device and at least one memory device, a bus system for transmitting memory requests to the memory device comprising:
- a plurality of bus lines for transmission of memory requests;
- a packet comprising a memory request for transmission across the bus lines, said packet comprising;
- a first word comprising a first portion of count information transmitted over a first group of bus lines, said count information indicating the count of blocks of data which are responsive to the memory request, and
- at least one additional word, subsequent to the first word, comprising additional portions of count information transmitted over the first group of bus lines;
- said memory device comprising receiving means coupled to each of the bus lines, wherein said group of bus lines is coupled to a group of receiving means, the number of bus lines utilized to transmit count information determined to minimize the number of crossings between spatial regions delineated by each of the receiving means;
- wherein the length of wiring between each of the group of the receiver means and therefore the length of wiring needed to process the count information received at the group of receiver means is minimized.
- 5. The digital system as set forth in claim 4, wherein a first portion of count information is transmitted in a third word transmitted as part of the packet and the second portion of count information is transmitted in a fourth word transmitted as part of the packet.
