Method and device for receiving sequential instructions
View Patent ↗A method of receiving a plurality of instructions. The method generally comprises the steps of (A) storing a first of the instructions in response to receiving the first instruction at an initial time, and (B) rejecting a second of the instructions that depends from the first instruction in response to receiving the second instruction greater than a maximum delay after the initial time.
1. A method of receiving a plurality of instructions, comprising the steps of:
(A) storing a first of said instructions in response to receiving said first instruction at an initial time;
(B) calculating a maximum delay as a predetermined multiplication factor times a period of said instructions; and
(C) rejecting a second of said instructions that depends from said first instruction in response to receiving said second instruction greater than said maximum delay after said initial time.
2. The method according to claim 1 , further comprising the step of rejecting said second instruction in response to receiving said second instruction less than a minimum delay after said initial time.
3. The method according to claim 2 , wherein a difference between said maximum delay and said minimum delay is approximately a predetermined period.
4. The method according to claim 3 , wherein said initial time is determined in units of said predetermined period.
5. The method according to claim 1 , further comprising the step of calculating a first new time by adding said initial time and said maximum delay.
6. The method according to claim 5 , further comprising the step of calculating a second new time in response to accepting said second instruction proximate said first new time.
7. The method according to claim 6 , further comprising the step of rejecting a third of said instructions that depends from said first instruction in response to receiving said third instruction later than said second new time.
8. The method according to claim 1 , further comprising the step of rejecting said second instruction in response to a disable signal assigned to said first instruction.
9. The method according to claim 8 , further comprising the steps of:
storing a third instruction that is independent of said first instruction in place of said first instruction in response to receiving said third instruction;
calculating a new time in response to receiving said third instruction;
storing said new time indexed by said third instruction; and
accepting a repeat instruction of said instructions in response to receiving said repeat instruction proximate said new time.
10. A device comprising:
a detector circuit configured to receive a plurality of instructions; and
a timing circuit configured to (i) store a first of said instructions received at an initial time, (ii) calculate a maximum delay as a predetermined multiplication factor times a period of said instructions and (iii) reject a second of said instructions that depends from said first instruction in response to receiving said second instruction greater than said maximum delay after said initial time.
11. The device according to claim 10 , wherein said timing circuit is further configured to reject said second instruction in response to receiving said second instruction less than a minimum delay after said initial time.
12. The device according to claim 11 , wherein a difference between said maximum delay and said minimum delay is approximately a predetermined period.
13. The device according to claim 12 , further comprising a clock circuit configured to generate a time signal in units of said predetermined period.
14. The device according to claim 10 , further comprising a memory configured to store a first new time determined by adding said initial time and said maximum delay.
15. The device according to claim 14 , wherein said timing circuit is further configured to calculate a second new time in response to acceptance of said second instruction proximate said first new time.
16. The device according to claim 15 , wherein said timing circuit is further configured to reject a third of said instructions that depends from said first instruction in response to receiving said third instruction later than said second new time.
17. The device according to claim 10 , further comprising a memory configured to store (i) said predetermined multiplication factor and (ii) said period of said instructions.
18. The device according to claim 17 , wherein said memory is further configured to store a disable signal assigned to said first instruction to block acceptance of said second instruction.
19. The device comprising:
means for (i) storing a first of a plurality of instructions in response to receiving said first instruction at an initial time and (ii) calculating a maximum delay as a predetermined multiplication factor times a period of said instructions; and
means for rejecting a second of said instructions that depends from said first instruction in response to receiving said second instruction greater than said maximum delay after said initial time.
