Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Fig. 1 shows the structure of the statistical counter provided by the present invention. The first-stage counter 101 periodically outputs the count value, and the number of the first-stage counter 101 is not limited, and can be increased or decreased according to actual needs. As an embodiment of the present invention, the first-stage counter 101 is implemented by using a register, and as another embodiment of the present invention, it may also be implemented by using a RAM.

[0026] The second stage counter 102 is realized by RAM, and the RAM is a dual-port, and one port is used to read the...

Abstract

The invention discloses a large-capacitance non-refreshed high-speed statistical counter in the core designing domain, which comprises the following parts: at least one first grade counter, gating element, accumulator, second grade counter, refreshing controller, wherein the second grade counter is RAM counter. The invention can satisfy large-quantity metering items with long refreshing period to proceed statistical application rapidly, which saves cost effectively.

Description

technical field [0001] The invention belongs to the field of chip design, in particular to a statistical counter. Background technique [0002] In chip design, the statistical counter is an essential functional module, which provides an important means for monitoring the state information inside the chip. For example, in a data communication chip, statistical counters are used to count the number of packets and traffic of each interface, or to count certain types of packets. [0003] When using statistical counters in chip design, the following requirements should be met: [0004] 1. The statistical counter must be able to quickly record the increased value. In order to be able to count accurately, the statistical counter must be able to increase the required count value every clock cycle. [0005] 2. The number of statistical counting items should be as many as possible. In order to obtain more statistical information inside the chip, the number of counters is increasin...
