*
* CURBE - constant URB entry. An urb region (entry) used to hold
* constant values which the fixed function units can be instructed to
- * preload into the GRF when spawining a thread.
+ * preload into the GRF when spawning a thread.
*
* VUE - vertex URB entry. An urb entry holding a vertex and usually
* a vertex header. The header contains control information and
* special and may be overwritten.
*
* MRF - message register file. Threads communicate (and terminate)
- * by sending messages. Message parameters are placed in contigous
+ * by sending messages. Message parameters are placed in contiguous
* MRF registers. All program output is via these messages. URB
* entries are populated by sending a message to the shared URB
* function containing the new data, together with a control word,
