Abstract
Embodiments of the present disclosure include techniques for moving data between electronic system components using buffers. A digital processor stores data generated in response to a series of commands in a first buffer. Commands are received with a reference to a second buffer. The digital processor tracks the last location that a data result was stored in the first buffer. When a data result fills the buffer, the remaining data is automatically stored in the second buffer. Downstream devices may empty full buffers. A client may receive an indication that a buffer is empty and subsequently send commands with a reference to empty buffer.
Claims21
1-20. (canceled)
A system comprising:
- memory comprising a first buffer and a second buffer;
- a digital processor that, in operation, receives a plurality of commands, the plurality of commands comprising a first command that includes a destination buffer identifier specifying the second buffer as an overflow buffer and a subsequent command that includes a continue-write indicator indicating that writing is to continue using a previously stored destination buffer identifier, the digital processor stores a plurality of data results produced by the plurality of commands in the first buffer and the second buffer by:
- storing the destination buffer identifier from the first command;
- in response to the continue-write indicator, continuing to write to the first buffer and using the destination buffer identifier to identify the overflow buffer;
- tracking a last location within the first buffer of a particular data result of the plurality of data results;
- storing a particular subsequent data result of the plurality of data results, after the particular data result, at a location after the last location within the first buffer, and responsive to a data result of the plurality of data results filling the first buffer, automatically storing a remainder of the data result and subsequent data in the second buffer using the destination buffer identifier.
3 more elements
A method comprising:
- receiving, in a digital processor, a plurality of commands;
- storing, by the digital processor, a plurality of data results produced by the plurality of commands in a first buffer and a second buffer of a memory, wherein individual commands of the plurality of commands independently include a destination buffer identifier specifying the second buffer as an overflow buffer;
- tracking, for the plurality of data results, a last location within the first buffer of a particular data result of the plurality of data results;
- storing a particular subsequent data result of the plurality of data results, after the particular data result, at a location after the last location within the first buffer;
- and
- responsive to a data result of the plurality of data results filling the first buffer, automatically storing a remainder of the data result and subsequent data results in the second buffer using the destination buffer identifier.
3 more elements
A method comprising:
- receiving, in an accelerator, a plurality of commands from a software client, the plurality of commands producing a plurality of data results having non-deterministic output sizes, wherein the commands are issued from the software client to the accelerator without waiting, in the software client, for an indication that the commands are done executing;
- storing, by the accelerator, the plurality of data results contiguously in a first buffer and a second buffer of a memory by tracking a last location within the first buffer of a particular data result of the plurality of data results;
- storing a particular subsequent data result of the plurality of data results, after the particular data result, at a location after the last location within the first buffer;
- responsive to a data result of the plurality of data results filling the first buffer, automatically storing a remainder of the data result in the second buffer and tracking successive locations in the second buffer;
- and
- storing subsequent data results after the data result sequentially in the second buffer, wherein data is stored sequentially across multiple buffers.
